Question

Solve, using the substitution method.

 

2x + 4y = 16

x – 7 = – 4y

arabpride · Answer

2x + 4y = 16
-2x            -2x

4y = -2x +16
/4           /4

y = -2/4 + 4
~~~~~~~~~~~
x - 7 = -4y
-x           -x

-7 = -x -4y
+4y         +4y

4y - 7 = -x
     +7     +7

4y = -x + 7
/4             /4

y = x/4 + 7/4
~~~~~~~~~~~~
