Short Answer

Expert verified

The solution is x=-52 orx=-1

Step by step solution

01

Step 1. Given information

Absolute value equation:4x+7+2=5

02

Step 2. Calculation 

We have,

4x+7+2=5

4x+7+2-2=5-2

4x+7=3

4x+7=-3 or 4x+7=3

role="math" localid="1644753496278" 4x+7-7=-3-7 or 4x+7-7=3-7

4x=-10 or 4x=-4

4x4=-104 or 4x4=-44

x=-52 orx=-1
