4y + 10 = -18 4y = -28 y = -7
(12, 1)
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
8x plus 4y equals 5 is 8x + 4y = 5.
How do you solve 4y plus x equals 8
x = 12, y = 1
-4x + 4y = 1
(4, 8)
-x + 4y = 8
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
No.
