Do a bit of rearrangement: 1: 10x + 2 = 8y; 2: 8y = 59 - 9x
so 10x + 2 = 59 - 9x so 19x - 57 making x = 3 and y is therefore 4.
10*6+8*7 = 116
x =6 y = 8 10x = 60 8y = 64 10x + 8y = 124
8y-7x
4x+8y=-24
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16
10*6+8*7 = 116
74 (10*5)+(8*3) = 74
x =6 y = 8 10x = 60 8y = 64 10x + 8y = 124
8y-7x
2x = -7 - 8y
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
12x-8y
4x+8y=-24
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16
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.
y = -1
The standard form is 3x - 8y - 4 = 0
