3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
2x + 8 + x = 2x + 15 simplify 2x to both sides since they have the same sign8 + x = 15 subtract 8 to both sidesx = 7
X=7
5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
6x - 8 + 2x - 5 = 7 - 2x ?
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
0
-5x+3(x+8)=16-2x
2x - 5 - 4x + 8= 2x - 4x - 5 + 8= -2x + 3
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
No. If that's -2x + 7 = -9 -2x = -16 x = 8
