## maddiemaze one year ago Use substitution to solve the system. x=2y+8 2x-3y=13

1. dmezzullo

erm, multiply the first equation by $$-2$$. that yields$\begin{cases}-2x = -4y - 16 \\ 2x - 3y = 13\end{cases}$add both equations and solve for $$y$$.

2. johnweldon1993

you already know what x equals...so sub it in for x in the second equation 2(2y+8) - 3y = 13 Now just distribute and simplify

3. johnweldon1993

dmezz thats elimination ...the problem asked for substitution :)

solve each system by the elimination method 1)3x+2y=10 2x+y=7 2)3x-2y=7 2x-y=8 3)2x+3y=-13 -4x+6y=-10

you already have the value of x from the first equation just substitute that value and get the answer
