Question

If someone could walk me through the steps on how to solve this I'll fan and medal.

Solve the following system of equations by using the elimination method.
x – y = 11
2x + y = 19
A. (1,10)
B. (-1,-1)
C. (12,2)
D. (10,-1)

Answer 1

I will try to solve your system of equations.
x−y=11;2x+y=19
Step: Solve x−y=11 for x:
x−y+y=11+y(Add y to both sides)
x=y+11
Step: Substitute (y+11) for x in 2x+y=19:
2x+y=19
2(y+11)+y=19
3y+22=19(Simplify both sides of the equation)
3y+22+−22=19+−22(Add -22 to both sides)
3y=−3
3y/3 = −3/3
(Divide both sides by 3)
y=−1
Step: Substitute (−1) for y in x=y+11:
x=y+11
x=−1+11
x=10(Simplify both sides of the equation)
Answer:
x=10 and y=−1
