6x - 4y
The solution pair is (-7, 22), demonstrated as follows: (1) x + y = 15 : given; (2)4x + 3y = 38 : given; (3)3x + 3y = 45 : equation (1), multiplied by 3; (4) x = -7 : equation (2), minus equation (3); (5) y = 22 : equation (1), minus equation (4).
If you mean 3y+24 = y-12 then the value of y works out as -18
(4, -7)
-2/3
12-3y = 15 -3y = 15-12 -3y = 3 y = -1
6x - 4y
The y-intercept is -5. 2x - 3y = 15 -3y = -2x + 15 y = 2/3x - 5 the y-intercept is the number in slope intercept form that does not have a variable, the minus sign makes the intercept negative.

2x+3y=13 3x-y=3 x=2
The numbers 3y times 18 equals 54. This is taught in math.
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
Slope = 5/3 = 1.66...
OK, so-3y + 15 - y = 39-3y + 15 - 15 - y = 39 - 15-3y -y = 24-4y = 24-y = 6y= -6.Hope this helps!
