For exercises 99-102, solve the equation. Use a calculator to do arithmetic. $$ \frac{3}{4} x+\frac{5}{9}=\frac{59}{50} $$

Short Answer

Expert verified
x = \(\frac{562}{675}\)

Step by step solution

01

- Subtract the constant term

Isolate the term with the variable by subtracting \(\frac{5}{9}\) from both sides of the equation: \(\frac{3}{4}x = \frac{59}{50} - \frac{5}{9}\)
02

- Simplify the right-hand side

Find a common denominator for \(\frac{59}{50} - \frac{5}{9}\). The common denominator for 50 and 9 is 450: \(\frac{59}{50} = \frac{59 \times 9}{50 \times 9} = \frac{531}{450}\) and \(\frac{5}{9} = \frac{5 \times 50}{9 \times 50} = \frac{250}{450}\). Now, subtract \(\frac{531}{450} - \frac{250}{450} = \frac{281}{450}\)
03

- Solve for x

We have \(\frac{3}{4}x = \frac{281}{450}\). To solve for \(x\), multiply both sides by \(\frac{4}{3}\): \(x = \frac{281}{450} \times \frac{4}{3} = \frac{1124}{1350}\)
04

- Simplify the fraction

Simplify \(\frac{1124}{1350}\) by finding the greatest common divisor (GCD). The GCD of 1124 and 1350 is 2. So divide both the numerator and the denominator by 2: \(\frac{1124 \div 2}{1350 \div 2} = \frac{562}{675}\)

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Algebraic Fractions
Algebraic fractions are fractions where the numerator, the denominator, or both contain algebraic expressions (which can include variables, numbers, or both). In simple terms, they are like normal fractions but with variables thrown into the mix. For example, in the equation \(\frac{3}{4}x + \frac{5}{9} = \frac{59}{50}\), both \(\frac{3}{4}x\) and \(\frac{5}{9}\) are algebraic fractions. Working with these requires a solid understanding of both fraction manipulation and algebraic principles. Remember: every time you see a fraction with a variable, it's an algebraic fraction.

When solving equations involving these, the goal is usually to isolate the variable term. This often involves dealing with the fractions first through operations such as addition, subtraction, multiplication, and division.
Simplifying Fractions
Simplifying fractions means reducing them to their simplest form so that the numerator and the denominator are as small as possible. This usually involves finding the greatest common divisor (GCD) of the numerator and the denominator and dividing both by that number.

For example, in the given solution, we start with \(\frac{1124}{1350}\). To simplify this, find the GCD (which is 2 in this case) and divide both the numerator and the denominator by that value:
  • \(\frac{1124 \text{ divided by } 2}{1350 \text{ divided by } 2} = \frac{562}{675}\).
  • This step ensures that the fraction is in its simplest form without changing its value.

    Simplifying fractions is crucial as it makes further mathematical operations easier and helps present the final answer more neatly.
