Answer:

x = 2 and y =10

Explanation:

Substitution is done by substituting one equation into another. To begin solve one equation for a variable. Both equations are already solved for a variable.

So substitute y = 5x into y = 4x + 2. Then solve for x.

5x = 4x + 2

x = 2.

Substitute x= 2 into one of the equations to solve for y.

y = 5(2) = 10

y=10.
