Answer:

Step 1: Make x the subject by moving all x terms to one side;

a)  4x-2x=7+3

Step 2; solve the linear equation

2x=10

x=10/2

x = 5

b) 2x-7x = -14-6

-5x = -20

x = -20/-5

x= 4

Hope this helps :) ! I'd apreciate if you'd mark my answer brainliest because ive been on the same rank for quite a loong time :(

A) 4x-3=2x+7

Let's say x is 5

4x5-3 = 2x5+7

20-3 = 10+7

17=17

So x is 5

B) 2x+6 =7x -14

Let's say x is 4

2x4+6 = 7x4-14

8+6= 28-14

14=14

So x is 4
