81x−3=6

24−2x=13

3x + 2 = 25

x3+7=8

4 + 5x = 18

Answer 1

its 81x-3=15 instead

Explanation:

I took the test and got 90% thinking it was 2x-3=15 but its not

Answer 2

The first one!

2x-3=15
Add 3 to both sides (this will cancel out the -3)
2x=18
Divide by two on each side (this will cancel out the 2)
X=18
