Question

X+5y=0
x+2y=15
by using Substitution​

Answer 1

To solve the system of equations using substitution, we can express one variable in terms of the other variable from one equation and substitute this into the other equation.

From the first equation, we can express x in terms of y:

x = -5y

Now we can substitute x = -5y into the second equation:

-5y + 2y = 15 -3y = 15 y = -15 / 3 y = -5

Substitute y = -5 into the first equation to find x:

x = -5*(-5) x = 25

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