you say: 5x+7=84-6x 5x+6x+7=84-6x+6x 11x+7=84 11x+7-7=84-7 11x=77 x=77/11 x=7

7x + 8 = 84 Subtract 8 from bith sides: 7x = 76 Divide both sides by 7: x = 76/7 = 10.8571428...
-7+x=13x the -7=12x and x =-7/12
7x + 8 = 84 7x = 84 - 8 x = 76/7 x = 10.8571

7 x 12 = 84
y=84-72=12 z=84-52=32 x=84-12-32=40
12 x 7 = 84
84/7 = 12, so 12 x 7 = 84
12 x 7 = 84

7x + 8 = 84 Subtract 8 from bith sides: 7x = 76 Divide both sides by 7: x = 76/7 = 10.8571428...
9 plus 7 equals 144. Generally, x plus y = x(x+y).
-7+x=13x the -7=12x and x =-7/12
7=x+1 6=x
