2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
x = 0 and y = 4
2x-4=6x+8-8= -82x-12= 6x-2x= -2x-12= 4x/4=/4-3=x
-2x + 2y = 4 is equivalent to twice -2 + y = 2 which is the equation of a straight line.
x equals 4
If x=4 then 2x+7 =
3x+56 = 2x+4 3x-2x = 4-56 x = -52
Do you need this equation factored or? 2x+3=x+4?
x=-4

2x-4
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
8
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2x+4 = -16 2x = -16-4 2x = -20 x = -10
2x+5=3x+1 -x=-4 x=4
