Answer:6
Step-by-step explanation:
-7+10-(-3)
Using BODMAS
-7+10+3
3+3=6
5 hours because 5x6 = 30 +20 =50
You can solve this system of the equations with graphical method or algebra method.
I solve this system with Gaus algorithm
first we divide second equation with number 3 and get x+10y=12
Than subtract first equation from second and get 5y=6 => y=6/5
now we replace y in the first equation and get x+5*(6/5)=6 =>x+6=6
=> x=0 (x,y)=(0,6/5)
Conclusion is that we have one intersection point between this two graphs.
Good luck!!!
