Solve the following system of

equations by substitution.
y = 5x
8x − 3y = 35

1 answer

Substitute y = 5x into the second equation:

8x - 3(5x) = 35
8x - 15x = 35
-7x = 35
x = -5

Now substitute x = -5 back into the first equation:

y = 5(-5)
y = -25

Therefore, the solution to the system of equations is x = -5 and y = -25.
