The solution to the systems of equations is (7, 3)
Given the systems of equations expressed as:
-x + 4y = 5 ....................1
x - 5y = -2 ...................... 2
Add both equations to have:
-x+x + 4y - 5y = 5 - 2
4y-5y = -3
-y = -3
y = 3
Substitute y = 3 into equation 1:
-x + 4(3) = 5
-x + 12 = 5
-x = 5 - 12
-x = -7
x = 7
Hence the solution to the systems of equations is (7, 3)

Answer:
74 hope this works if not I'm sorry
Triangle
m<A + m<B + m<C = 180
8x +12 + 5x+14 + <span>2x +4 = 180
15x + 30 = 180
15x = 180 -30
15x = 150
x = 10
m<A </span><span>= 8x +12
</span>m<A = 8(10) +12
m<A = 80 + 12
m<A = 92
answer
m<A = 92
