3x-4x=12 that means -x equals 12 so x equals -12
4y + 19 = 74y = 7-194y = -124y/4 = -12/4y = -3
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
That depends what the value of y is.
If you mean: 3+2x = 12 and 4y-x = 5 then their values are x = 4.5 and y = 2.375
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
3x-4x=12 that means -x equals 12 so x equals -12
4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
4y + 19 = 74y = 7-194y = -124y/4 = -12/4y = -3
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
42+4y -12 = 13y -12 -2y 4y -13y+2y = 12 -12 -42 -7y = -42 y = 6
That depends what the value of y is.
If you mean: 3+2x = 12 and 4y-x = 5 then their values are x = 4.5 and y = 2.375
4y-8x = 12 4y = 8x+12 y = 2x+3 So the slope is 2 and the y intercept is 3
(0,-4)
(4, -2)
x = 4 and y = 0
