You have to find x and y
substitution is the easiest method so i will solve it by that
4y=-5x-83
y=-5/4x - 20.75
3x-3(-5/4x - 20.75)=-12
3x+3.75x+62.25=-12
6.75x=-74.25
x=-11
y=-5/4(-11) - 20.75
y=-7
Your answers are x=-11 and y=-7
x = 4 and y = 0
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
That depends what the value of y is.
4y + 19 = 74y = 7-194y = -124y/4 = -12/4y = -3
4
There are 4.
x = 4 and y = 0
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
That depends what the value of y is.
4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
4y + 19 = 74y = 7-194y = -124y/4 = -12/4y = -3
4
8x plus 4y equals 5 is 8x + 4y = 5.
(4, -2)
(12, 1)
y=4
