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
3
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
y=2 + 3x seems like a linear equation, therefore, y=3x + 2.The gradient is 3.

3x-2 = 2x+3 3x-2x = 3+2 x = 5
The answer is -7
