solve the system of equations by substitution. y= 5x and 8x - 3y = 35

Answer 1

First, we need to substitute y with 5x in the second equation:

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

Now, substitute x = -5 back into the first equation to solve for y:

y = 5(-5)
y = -25

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