Answer:
x = -12
Step-by-step explanation:
Remember that ax + bx = (a+b)x
-10x + 9x = 12
Add -10x and 9x together
(-10 + 9)x = 12
-x = 12 (-1x is written as -x, just as 1x is written as x)
÷ -1 both sides
x = -12
I hope this helps. Happy studying. :)

Answer:
(-3,2)
Step-by-step explanation:
To solve this, I will use substitution. First, isolate y in one of the equations;
-2x+y=8
-3x-y=7
-2x+y=8 is the same as y=2x+8, Now plug y into the other equation to solve for x;
-3x-(2x+8)=7 Solve for x
-5x-8=7
-5x=15
x=-3, Now plug in x in either equation to solve for y;
-2(-3)+y=8
6+y=8
y=2, The answer to this system is (-3,2)
