6X + 3 = 2X + 19Subtract 3 from each side:6X = 2X +16Subtract 2X:4X = 16Divide by 4X = 4
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
6x - 3 = 2x + 1Add 3 to each side:6x = 2x + 4Subtract 2x from each side:4x = 4Divide each side by 4:x = 1
2x + 3 = 92x = 9 - 32x = 6x = 6/2x = 3
6x - 3 = 2x + 1Add 3 to each side:6x = 2x + 4Subtract 2x from each side:4x = 4Divide each side by 4:x = 1
6X + 3 = 2X + 19Subtract 3 from each side:6X = 2X +16Subtract 2X:4X = 16Divide by 4X = 4
6x + 3 = 2x + 5 4x = 2 x=1/2
x would be -3
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
6x - 3 = 2x + 1Add 3 to each side:6x = 2x + 4Subtract 2x from each side:4x = 4Divide each side by 4:x = 1
2x-4=6x+8-8= -82x-12= 6x-2x= -2x-12= 4x/4=/4-3=x
2x + 3 = 92x = 9 - 32x = 6x = 6/2x = 3
6x - 3 = 2x + 1Add 3 to each side:6x = 2x + 4Subtract 2x from each side:4x = 4Divide each side by 4:x = 1
6x + 8 = 6 6x = -2 x = -2/6 x = -1/3
common it's very easy !!2x + 3 = 92x = 6x = 6/2x = 3
6x - 3y = 6 y= 2x + 5 replace 2x + 5 for y into the first equation 6x - 3y = 6 6x - 3(2x + 5) = 6 6x - 6x - 15 = 6 0 - 15 = 6 -15 = 6 False So the system has no solution.
6x + 3 = 3(2x + 1)
