Line 3

Step-by-step explanation:

we have

4(2x+3)=-20

Verify each line

Line 1

4(2x+3)=-20 ----> the given equation

Line 1 is correct

Line 2

Distribute in the left side

8x+12=-20

Line 2 is correct

Line 3

Subtract 12 both sides

8x=-20-12

8x=-32

The line 3 is not correct

Multiply each side of your equation by 24.

Then one side of it will be 'x',and the other side will be the value of 'x'.
(It will be in the form of a fraction, which you may want to simplify.)
