Use substitution to solve the system.
-4x + 3y = 19
y= 3x + 13

x=
y=

Answer 1

-4

Explanation:

16+3y=19

-16 -16

3y=3

--------

3 3

y=1

1=-12+13

1=1

Answer 2

-4x + 3y =19
Y= 3x + 13

-4x + 3(3x + 13) =19

-4x + 9x + 39 =19

5x + 39 =19
-39 -39

5x = -20
Divide by 5 on both sides
Then you get
X = -4
