Solve the system of equations by using the substitution method. Check each solution. Show your work.
3x + 2y = 6
x + 4y = -8

Question

cwrw238 · Answer

from second equation 
x = -8 - 4y

now substitute for x in the first equation
3(-8-4y) + 2y = 6
-24 - 12y + 2y = 6
-10y = 30


can you continue?

find value of y from the last line then plug this into the second equation to find x

then plug the values of x and y into both the original equations to see if they fit.
