Equation: -3+2x = -x + 6
Like Terms:
2x + (x) = 6 + (3)
Move the -x to the left (becomes +x) and move the -3 to the right (becomes +3)
We now have:
3x = 9
Divide both sides by 3:
(3x)/3 = 9/3
The solution is:
x = 3
Check:
-3 + 2(3) = -(3) + 6
-3 + 6 = 6 - 3
0 = 0, solution is correct
-2x+3+1=-7 -2x=-11 x=11/2
(2x + 3)(2x + 3)
2x = x+3 2x-x = 3 x = 3
(0, -3)
2x = 4x + 3 -2x = 3 x = -3 / 2
2x+3 = -11 2x = -11-3 2x = -14 x = -7
-2x+3+1=-7 -2x=-11 x=11/2
(2x + 3)(2x + 3)
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
2x = x+3 2x-x = 3 x = 3
(0, -3)

the converse of this conditional is true
2x = 4x + 3 -2x = 3 x = -3 / 2
2x=x+3=x=3
x=3
