Question

Solve the system of equations.
y = 9x
y= 2x+56

Answer 1

(8, 72)

Explanation:

Here we have two separate equations for y: y = 9x and y = 2x + 56.

Equating these equations eliminates y temporarily; we get:

9x = 2x + 56, or 7x = 56. Dividing both sides by 7 results in x = 8.

Then, by the first equation, y = 9(8) = 72.

The solution is (8, 72).
