Answer:
y=63, x=20, x=47, b=70, c=89, x=133
Step-by-step explanation:
1) y=63- alternate angles are the same
2) 4x+5x=180
9x=180
x=20
3) x=47
4) b=70- angles on a line equal to 180
c=89- angles in a triangle add up to 180
5) x=133- angles that are alternate are the same
20x-18y
26x-2(3x+4y)-10y
26x-6x-8y-10y
20x-18y go doawnload the app photomath its a great tool

I think the answer is...
26
X=-2
4x-2(-3x)= -20
4x+6x=-20
10x=-20
/10 /10
x=-2
Hope this helps!
