Answer:
x=-2.25,y=-2.25
Step-by-step explanation:
The given system is

We want to solve the system for x and y that makes the system true.
Let us multiply the first equation by 3 while maintaining the second equation:

Subtract the current second equation from the first one.

Divide through by 12:

From the second equation we have:

This implies that:

76 degrees. Angle y is supplementary to angle “2x+20”.
I'm pretty sure the answer is 12.
