7x+x = 8x
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
8x-2 = -9+7x8x-7x = -9+2x=-7
x=1
X = -3
-3.........
8x + 33 = 7x + 27 Subtract 7x from both sides: x + 33 = 27 Subtract 33 from both sides: x = -6
28=8x+12-7x 28=8x-7x+12 28=x+12 28-12=x+12-12 16=x
(1, -1)
the empty set.
x=-7
3x + 17 + 5x = 7x + 10Combine (add) the 'x'-terms on the left side of the equation:8x + 17 = 7x + 10Subtract 17 from each side:8x = 7x - 7Subtract 7x from each side:x = -7
