Answer:
undefined/no solution
Step-by-step explanation:
you use elimination to solve. So multiply 2x+4y=-12 by 1 and x+2y=-2 by 2. then you subtract 2x+4y=-12 by 2x+4y=-4 and get 0y=-8. Anything divided by 0 is undefined/no solution because you can't divide anything by 0.
Answer:
-10 is the answer
Step-by-step explanation:
first things that you will replace each number in:
-2x3+(-4)=-10
Distributive property: a(b+c)=ab+ac
expand form.
do parenthesis first it's got to be remove.

subtract by 9 both sides of an equation.

simplify by equation form.

then you subtract by 8x both sides of an equation.

simplify by equation form again.

therefore, you can also divide by -12 both sides of an equation.

finally, simplify equation.

Hope this helps!
