The correct answers would be a b and 2 because I don’t know this is a test to be honestly
Answer:
Step-by-step explanation:
5x-9y=-65
10x-3y=20
Multiple the first equation by 2
10x-18y=-130
10x -3y=20
Then subtract the two equations to get rid of the x
21y=-150
Divide the -150 by 21
Y=-7.14
Plug the y into the original equation. (Either one)
5x-9(-7.14)=-65
5x-64.28=-65
Then add 64.28 to the -65
5x=-0.72
Divide by 5
X=-0.144
I hope this is right
Answer:
92776
Step-by-step explanation:
FIrst multiply:
9*10000= 90000
2*1000=2000
70*10= 700
Then add:
90000+2000+700+70(already given)+6(already given)= 92776
Hope this helps! :)
