Question

Y = x + 15y = 2x Use substitution to solve the system of equations.

Answer 1

x = 15, y = 30

Step-by-step explanation

We want to solve the system of equations by substitution method.

We have that:

y = x + 15

y = 2x

Substitute the value of y in the second equation into the first:

=> 2x = x + 15

Collect like terms:

2x - x = 15

x = 15

Recall that:

y = 2x

=> y = 2(15)

y = 30

The solution to the system of equations is: x = 15, y = 30
