Chapter 1: Problem 57

Simplify each algebraic expression. $$7 x+(-5 y)+(-9 x)+19 y$$

Short Answer

Expert verified
The simplifed form of the expression is \((-2x)+14y\).

Step by step solution

01

Identify like terms

Like terms are terms that have the same variables raised to the same power. Here, \(7x\) and \(-9x\) are like terms since they both contain the variable \(x\). Similarly, \(-5y\) and \(19y\) are like terms since they both contain the variable \(y\).
02

Combine like terms

Add or subtract the coefficients of like terms together. Combining the like terms gives us \((-2x)+14y\).
03

Write the final simplified expression

The simplifed form of the expression is hence \((-2x)+14y\).
