Short Answer

Expert verified

The solution set of x is:-169

Step by step solution

01

Step 1. Given information 

An equation,86+3x=4

02

Step 2. Required to find 

Solve the given equation to find x.

03

Step 3. Solving the equation

Given, 86+3x=4

role="math" localid="1646572365203" 鈬�23(6+3x)=22

鈬�3(6+3x)=2

鈬�18+9x=2

role="math" localid="1646572555255" 鈬�9x=2-18

鈬�9x=-16

鈬�x=-169
