Let's solve your system by substitution.

x−3y=−1;2x−4y=2

Step: Solvex−3y=−1for x:

x−3y=−1

x−3y+3y=−1+3y(Add 3y to both sides)

x=3y−1

Step: Substitute3y−1forxin2x−4y=2:

2x−4y=2

2(3y−1)−4y=2

2y−2=2(Simplify both sides of the equation)

2y−2+2=2+2(Add 2 to both sides)

2y=4

2y

2

=

4

2

(Divide both sides by 2)

y=2

Step: Substitute2foryinx=3y−1:

x=3y−1

x=(3)(2)−1

x=5(Simplify both sides of the equation)

Answer:

x=5 and y=2
