Solve the system of equations. \begin{aligned} & -10x+3y = 5 & x=y-4 \end{aligned} −10x+3y=5 x=y−4

x = 1

y = 5

Step-by-step explanation:

You can use either substitution or elimination for this problem. I will use substitution.

Step 1: Replace x in the 1st equation

-10(y-4) + 3y = 5

-10y + 40 + 3y = 5

-7y = -35

y = 5

Step 2: Plug y into an original equation to find x

x = 5 - 4

x = 1

And you have your final answers!
