Question

What belongs in the box marked with the question mark in the proof?
Given: 4x + 1 = 6x - 2, Prove: x = 3/2
Statement/Reason
(1) 4x + 1 = 6x - 2
(2) 4x + 3 = 6x
(3) 3 = 2x
(4) 3/2 = x ?
(5) x = 3/2

Answer 1

4x+1=6x-2
4x+3=6
3=2x
3/2=2x/2, because you have to divide 2 from both sides
X=3/2
