You can put this solution on YOUR website!
x− 3y = −11
4x + 5y = −10


4x-12y=-44
4x+5y=-10


4x=12y-44
4x+5y=-10


The substitution:
(12y-44)+5y=-10
17y-44=-10
17y=34
y=2
and you can use this to find x.

Solve the system of equations using the substitution method and state your solution.
x− 3y = −11
4x + 5y = −10
x − 3y = − 11_____x = - 11 + 3y ------ eq (i)

4x + 5y = − 10 ------ eq (ii)

4(- 11 + 3y) + 5y = - 10 -------- Substituting - 11 + 3y for x in eq (ii)

- 44 + 12y + 5y = - 10

17y = 34

Now, substitute 2 for y in eq (i) to find the value of x.
