solve the following system of equation by substitution

Question

y = 5x
8x - 3y = 35

Answer 1

First, we can substitute y = 5x into the second equation:

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

Now that we have found x, we can substitute x = -5 back into the first equation to find y:

y = 5(-5)
y = -25

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