Step 1) Solve the second equation for

x

:

x

+

3

y

=

5

x

+

y

=

5

y

x

+

0

=

5

3

y

x

=

5

3

y

Step 2) Substitute

5

3

y

for

x

in the first equation and solve for

y

:

=

2

y

=

2

Step 3) Substitute

2

for

y

in the solution to the second equation at the end of Step 1 and calculate x:

x=−5−(3×−2)

x=−5−(−6)

x=−5+6

x=1

The solution is x=1 and y=−2
