Answer:
ahhhh reallly suck but im try it probably 7 /6 mabye i dont knowww.....
Can help me plzz f) i) dont need
x should equal -2 and y should equal -3 to solve this i multiplied the first equation by 2 then got rid of the 4y and -4y then i added the 14x to the 9 equaling 23x and added the -40 to the -6 which became 23x=-46 i solved this getting -s for x, then i plugged that into the equations to get y which was -3
X=12
Hope this helps
10x-20+6x+8=180º
