Answer 2

The correct answer is B
Explanation:
Step: Solvex+3y=13for x:
x+3y=13
x+3y+−3y=13+−3y(Add -3y to both sides)
x=−3y+13

Step: Substitute−3y+13forxin−2x+6y=22:
−2x+6y=22
−2(−3y+13)+6y=22
12y−26=22(Simplify both sides of the equation)
12y−26+26=22+26(Add 26 to both sides)
12y=48
12y/12=48/12(Divide both sides by 12)
y=4

Step: Substitute 4 for y in x=−3y+13:
x=−3y+13
x=(−3)(4)+13
x=1 (Simplify both sides of the equation)

Answer:
x=1 and y=4
