12x - 9y = 6, 12x + 20y = 64 29y = 58 y = 2 x = 2
1: 12x - 9y = 6 2: 12x + 20y = 64 Subtract 1 from 2: 29y = 58 y = 2. So does x.
The answer is 64.
X equals to 8
8x8 = 64 so it is 64 (the y) 3x4 = 12 so it is 12 (the x) 64+12 is 76.
12x - 9y = 6, 12x + 20y = 64 29y = 58 y = 2 x = 2
1: 12x - 9y = 6 2: 12x + 20y = 64 Subtract 1 from 2: 29y = 58 y = 2. So does x.
Subtract 3y from each side: -8 = 12y + 64Subtract 64 from each side: -72 = 12yDivide each side by 12: -6 = yie y = -6
The answer is 64.
