3x + 2 = 0 3x = -2 x = -2/3
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
3
The answer is -7
x+7=3x+3 4=2x 4/2=2 x=2
3x + 2 = 0 3x = -2 x = -2/3
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
x = 7 and 2/3
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2

3x-2 = 2x+3 3x-2x = 3+2 x = 5
The answer is -7
x+7=3x+3 4=2x 4/2=2 x=2
(-1, 0)
x-2=3x+1 x=3x+1+2 x-3x=3 -2x=3 x=-3/2
