2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
2x+3=3x-3 2x-3x=-3-3 -x=-6 x=6
3x+4 = 2x-3 3x-2x = -3-4 x = -7
According to my calculations, yes. 2x+8=3x+11 -8 2x=3x+3 -2x 0=x+3 -3 -3=x
Both equations are equal and so: 3x+1 = 2x+3 3x-2x = 3-1 x = 2 and by substituting y = 7
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
2x+3=3x-3 2x-3x=-3-3 -x=-6 x=6
3x+4 = 2x-3 3x-2x = -3-4 x = -7
If 3x + 3 = 2x + 6 then 3x - 2x = 6 - 3 x = 3
According to my calculations, yes. 2x+8=3x+11 -8 2x=3x+3 -2x 0=x+3 -3 -3=x
3x-2 = 2x+3 3x-2x = 3+2 x = 5
Both equations are equal and so: 3x+1 = 2x+3 3x-2x = 3-1 x = 2 and by substituting y = 7
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
2x+3y=13 3x-y=3 x=2
x = -7
