Answer:
A. no solution
Step-by-step explanation:
Given:
Isolate the term of x and y from one side of the equation.
x-y=-4 and -2x+2y=6
x-y=-4
First add by y from both sides.
x-y+y=-4+y
Solve.
x=-4+y
You have to substitute of x=-4+y.
[tex]\sf{-2\left(-4+y\right)+2y=6}[/tex]
Solve.
Use the distributive property.
Distributive property:
⇒ A(B+C)=AB+AC
-2(-4+y)
Multiply expand.
-2*-4=8
-2*y=-2y
Rewrite the expression down.
8-2y
8-2y+2y=6
-2y+2y=0
8=6
[tex]\Longrightarrow: \boxed{\sf{\text{\sf{NO solution}}}}[/tex]
- Therefore, the correct answer is "A. No solution".
