From the first equation we get
y=4x-15
put the value of y in the second equation
3x+2(4x-15)= -8
3x+8x-30= -8
11x=22
x=2
now put x=2 in any one eqn , say in first
4(2)-y=15
8-y=15
-y=7
y=-7
hope you understand!
X=59 all triangles have a sum of 180. So we subtract our given. 180 - 74 = 106. Then we subtract our givin again. 106 - 47 and boom our answer is 59.
