Find the solution of this system of equations
6x=90+9y
x-3y=50

The correct answer would be (-20, -23.3)

Step-by-step explanation:

To solve this, start by solving the first equation for x.

6x = 90 + 9y

x = 15 + 1.5y

Now that we have this, input the value for x in the second equation.

x - 3y = 50

(15 + 1.5y) - 3y = 50

15 - 1.5y = 50

-1.5y = 35

y = -23.3

Now input that value for y and solve for x.

x - 3y = 50

x - 3(-23.3) = 50

x + 70 = 50

x = -20

im not preaty sure about that
