Solve the system of equations.

- 5x + 2y = 9

y = 7x

Show Calculator

x=1 y=7

Step-by-step explanation:

Since y=7x, you substitute y in the first equation for 7x, that way the first equation becomes - 5x + 2 (7x) = 9

-5x + 14x = 9

9x = 9

x=1

Now you can find y from the second equation

y=7x

y=7*1

y=7
