Question

Explain the mistake made

in the work shown below.
8x + 22 = 2x + 42
10x + 22 = 42
10x = 20
x=2

Answer 1

step 2

Explanation:

8x + 22 = 2x +42

8x - 2x +22 =42

6x + 22 = 42

6x = 42 -22

6x = 20

x = 20÷ 6

x = 10/3

Answer 2

The added both 8x+2x when they were suppose to subtract 8x-2x

8x+22= 2x+42

6x= 42-22

6x= 20

x= 3.3 repeating
