Answer: D
Step-by-step explanation:
Let's take one of the equations and solve for a variable to use the substitution method.
Now replace this in the first equation.
Separate the terms.
Solve 20/5
Subtract 4 from both sides to isolate y.
Solve the difference.
Multiply by the reciprocal or the inverted fraction that is next to y to isolate it.
Now, in order to find x, replace y in any of the two equations.
