It is 8y - 8.
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16
13y+3z+8
10*6+8*7 = 116
2 - 8y + 6 = 4y - 702 + 6 + 70 = 4y + 8y78 = 12yy = 78/12y = 6.5
It is 8y - 8.
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16
13y+3z+8
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
10*6+8*7 = 116
(8x-8y)/(8x+8y) = (x-y)/(x+y)Cancel down by 8; you have simplified the equation.
7 pigs - 8 chickens + 9 pigs = 16 pigs - 8 chickens7 exes - 8 wyes + 9 exes = 16 exes - 8 wyes7x - 8y + 9x = 16x - 8y
x = 2, y = 84x + 8y= 4(2) + 8(8)= 8 + 64= 72
2 - 8y + 6 = 4y - 702 + 6 + 70 = 4y + 8y78 = 12yy = 78/12y = 6.5
It is the same as 8y+8z
It is like saying, "How much is 8 yams plus 2 yams plus 3 yams?" Add the numbers: 8+2+3 = 13. The answer is the number of yams. 8y+2y+3y = (8+2+3)y = 13y.
