Neither are multiple choice questions.

the solution to a system is an that solves both equations.

a solution to a systems of linear equation is the point where the lines

1. The solution to a system is an ordered pair that solves both equations.  

2. A solution to a systems of linear equation is the point where the lines intersect

Step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

the answer is stop cheating on things stoopid
