What is the solution to the system of equations below? y= -4/5 x + and y = –30
Naya [18.7K]

Answer:

x=37.5

Step-by-step explanation:

We need to find the solution to the following system of equations:

y = -\frac{4}{5} x and y=-30

By plugging the value of 'y' into the first equation we have that:

-30 = -\frac{4}{5} x ⇒ 30=\frac{4}{5} x

Solving for 'x' we have:

x=37.5

So, the solution to the system of equation is: (37.5, -30)
