Chapter 2: Q4. (page 86)

Evaluate the following equation and check the solution is correct or not:

鈭�4+t=鈭�7

Short Answer

Expert verified

The solution of the equation 鈭�4+t=鈭�7is t=鈭�3.

Step by step solution

01

Step 1. Given information.

The given equation is 鈭�4+t=鈭�7.

02

Step 2. Write the concept.

In an equation, the variable represents the number that satisfies the equation.

To solve an equation means to find the value of the variable that makes the equation true.

If an equation is true and the same number is added to each side of the equation, then the resulting equivalent equation is also true.

03

Step 3. Solve the equation.

The equation 鈭�4+t=鈭�7can be solved below:

鈭�4+t=鈭�7

Add 4 of both sides in the above equation.

鈭�4+t+4=鈭�7+4t=鈭�7+4

So,

t=鈭�3

04

Step 4. Check the solution.

Take the equation 鈭�4+t=鈭�7.

Substitute t=鈭�3on the right-hand side of the equation.

鈭�4+t=鈭�7鈭�4+鈭�3=鈭�7鈭�4鈭�3=鈭�7鈭�7=鈭�7

This shows that, t=鈭�3is the solution of the given equation.

A hang glider 25 meters above the ground starts to descend at a constant rate of 2 meters per second. Which equation shows the height h after t seconds of descent?

  1. h=25t+2t
  2. h=鈭�25t+2
  3. h=2t+25
  4. h=鈭�2t+25

Compare and contrast solving equations with variables on both sides of the equation to solving one-step or multi-step equations with a variable on one side of the equation.
