Answer:
y=12
Step-by-step explanation:
12=24-y
step 1
subtract each side by 24
24-24 cancels out
12-24=-12
now we have
-y=-12
we now have to divide by -1
-1/-1=1
-12/-1=12
so we can conclude that y=12
Answer:
Low estimate
Step-by-step explanation:
2 5/6 rounded is 3 so the total would be 11 hours if everything is rounded.
So for eliminating, you only solve for one variable first.
I solved for y, so I multiplied by -4 to eliminate the x.
Then I got y= -1
I then substituted that to one of the equations to get x.
