solve by substitution
y=5x
8x-3y=35
show work
First, we 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 it back into the equation y=5x to find y:
y = 5(-5)
y = -25
Therefore, the solution to the system of equations is x = -5 and y = -25.
