9a-2b=-8.....1
-7a+3b=12.....2
So,
1 equation into 3 and 2 equation into 2.
Then,
18a-6b=-24
-14a+6b=24.
4a=0 a=0 .
Substitute a value in 2 equation.
b=4.
Hope it helped

But if you look at the way that triangle NVU is oriented in its appearance, it's laying on its side. We need to set it upright so that angle N is the vertex angle, angle V is the base angle on the left, and angle U is the base angle on the right. When we do that we see that sides NV and NM are corresponding and exist in a ratio to one another; likewise with sides VU and ML. Setting up the proportion:
