Question

solve the method of substitution:
1) 2x+y=5
x+3y=5​

Answer 1

Answer:

First subtract 2x from both sides of the second equation to get:

y=11−2x

Substitute this express for y

into the first equation to get:

−5=x−3y=x−3(11−2x)=x−33+6x

=7x−33

Add 33 to both ends to get:

7x=28

Divide both sides by 7 to get:

x=4

Then

y=11−2x=11−(2×4)=11−8=3
