Question

Help with #7 please :) i’ll mark you brainily

Answer 1

x = 11

Explanation:

The student didn't divide two on both sides in the step 1. This the mistake that the student made.

The correct solution

2√( 3x + 3 ) = 12

Divide 2 on both sides,

2√( 3x + 3 ) / 2 = 12 / 2

√( 3x + 3 ) = 6

Square on both sides,

[ √( 3x + 3 ) ]² = 6²

3x + 3 = 36

3x = 36 - 3

3x = 33

x = 33 / 3

x = 11

Answer 2
