8x+7=55 8x=55-7 8x=48 x=48/8 x=6
x=7 and y=4
8x+7=55 8x=55-7 [subtract 7 from both sides] 8x=48 x=48/8 [divide both sides by 8] x=6
7/8x = 21 7 = 21*8x 168x = 7 x = 7/168 = 1/24
8x + 3 = 50 8x = 47x = 47/8x= 5 and 7/8ths

If: -9-4x = 7-8x Then: x = 4
7 - 8x = 17 7 - 8x - 7 = 17 - 7 -8x = 10 -8x/-8 = 10/-8 x = -10/8 = - 5/4
