# Chapter 4 - An Introduction to Functions - 4-4 Graphing a Function Rule - Standardized Test Prep: 45

#### Work Step by Step

$2(x-5) = 2-x$ Distribute the 2 on the left side so you multiply x by 2 and -5 by 2 $2x-10 = 2-x$ Collecting like terms on the same side (move the x variable on left side and constant on right side) $2x+x = 2+10$ Combine like terms $3x = 12$ Isolate x by dividing 3 from both sides $\frac{3x }{3}= \frac{12}{3}$ Simplify x= 4 Therefore the solution is 4
