First we'll multiply the second equation by -2

Now let's add the new equation and the first one.

We found y's value. We'll plug it in one of the equations to find x's value.

Solution ;
(9, -6)
120-36 = 84 <==== what he has left
84/120×100% = percentage of what he has left
70% = percentage aka answer.
A straight line equals 180 degrees, so the 3 angles in the picture need to equal 180.
X + 90 + 25 = 180
x +115 = 180
Subtract 115 from both sides:
x = 65
