Solve the following system if equations by substitution .

Question

y = 5x

8x - 3y = 35

Answer 1

First, we substitute the first equation into the second equation:

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

Now that we have found the value of x, we can substitute it back into the first equation to find the value of y:

y = 5(-5)
y = -25

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