Equation 1 + equation 2
3x-8y +(-3x+10y) = 9+(-15)
2y= -6
then y=-3
from equation 1
3x-8y=9
3x-8(-3)=9
3x+24=9
3x=9-24=-15
then x=-5
I think the answer is 140, because in the question is asked twice angle R, so I multiplied 70 x 2= 140.
Answer= 140
Hope this helps!!

Answer:
The answer to your question is (2,12). Hope you have a nice day.
Step-by-step explanation:
So, first you put in the x value. 8(2)-y=4, 16-y=4. Then you subtracted 4 from each side. 4-4=0 and 16-4=12. 16-12=4.
Ƒ(x)=3x^3+12x^2+3x-18 = 3(x-1)(x+3)(x+2)
