Answer:

x = 2; y = 10

Explanation:

y = 5x

2x + 3y = 34

You have a system of equations. Since the first equation is already solved for y, we can easily use the substitution method. Substitute 5x for y in the second equation.

2x + 3y = 34

2x + 3(5x) = 34

2x + 15x = 34

17x = 34

x = 2

Now substitute 2 for x in the first equation.

y = 5x

y = 5(2)

y = 10

Solution: x = 2; y = 10
