Answer:
(3,2)
Step-by-step explanation:
Let's solve this via elimination method:

By subtracting equation 2 from equation one we obtain:

Next we can use any equation either 1 or 2 to determine what x is, I'll use equation 1. Let y=2 and so:

Therefore the solution for the system of equations is:
x=3 and y = 2 as an ordered pair we have (3,2)

The answer is D
Answer:
Y= 20
X= 25
Step-by-step explanation:
The angles of a triangle have to equal 180
So
80+60 = 140
180 - 140 = 40
40/2 = 20
Y = 20
The angles of a linear line split equal 180
So
2y is one side of it which we learned Y = 20 which makes that side 40
To find the other side just guess and check
6(25) = 150
150 - 10 = 140
So the 2y = 40 and the (6x-10) = 140
So yea boom done
