Question

Solve each system by substitution.
1) -3x + y=-13
3x + 4y = 8

Answer 1

x= 4 y= -1

Explanation:

if you multiply -3 by 4 it equals -12 then add -1 to get - 13 for the first equation.

for the second equation you multiply 3 by 4 to get 12 and multiply 4 by -1 to get -4 then you add them together to get 8. start with a process of elimination by substituting each eqation with 0.
