2x-4=6x+8-8= -82x-12= 6x-2x= -2x-12= 4x/4=/4-3=x
2x+9=6x-3 Therefore 4x=12 -->x=3
5x + x - 6x + 2x = 2x
2x + 6x + 4x = 12x
12+2x = 6x-18 12+18 = 6x-2x 30 = 4x Divide both sides of the equation by 4 to find the value of x: x = 7.5
2x-y=4
6x - 8 + 2x - 5 = 7 - 2x ?
4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
6X + 3 = 2X + 19Subtract 3 from each side:6X = 2X +16Subtract 2X:4X = 16Divide by 4X = 4
y=6x-16 y=-2x+8
