Question

Use the substitution method to solve the following system of linear equations:

2x + 2y = 10
x = –y + 5

A.
There are an infinite number of solutions.

B.
The solution is (4, –1).

C.
The solution is (2, –3).

D.
There is no solution.

Answer 1

2x + 2y = 10 --- reduce by dividing by 2
x + y = 5
x = -y + 5
same as the other equation...so infinite solutions

Answer 2

Thank you so much!

Answer 3

YW so much...lol
