10*6+8*7 = 116

74 (10*5)+(8*3) = 74

x =6 y = 8 10x = 60 8y = 64 10x + 8y = 124

12x-8y

8y-7x

2x = -7 - 8y

If x equals 10 and y equals 10, then 9x plus 8y equals 170.

-3x-8y=4

4x+8y=-24

If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16

y = -1

-1

No, that is a equation.

y equals 3

The standard form is 3x - 8y - 4 = 0

9y-3y=6y; 6y+2y=8y; so your answer is 8y

The standard form is 3x + 8y + 4 = 0

Y- intercept of 4x+8y=16

Yes.

x2 + 2y - 6x + 8y - 1 = x2 - y2 + 4x + 6y - 1 y2 - 10x + 4y = 0 y(y+4) = 10x It cannot be solved completely because with two variables (x and y) you need two independent equations for a full solution.
