Answer:
x=-1, y=-7
Step-by-step explanation:
8x-2y=6
3x+3y=-24
Multiplying the topmost equation by 3/2:
12x-3y=9
3x+3y=-24
Adding the two equations together:
15x=-15
x=-1
Plugging this back into a previous equation:
8(-1)-2y=6
-8-2y=6
-2y=14
y=-7
Hope this helps!
I'm not sure if this is the answer you are looking for, but the number before a variable is called a coefficient.

Answer:
(6,2)
Step-by-step explanation:
y=-1/2x+5
y=2x-10
-1/2 x+5 =2x-10 to find the solution y=y ( point of intersection of two lines)
-1/2 x-2x = -10-5 solve for x
-5/2 x=-15
x=-30/-5=6
y=2x- 10 substitute x in the equation to get y
y=2(6)-10
y=2
