Answer:

7y = 56

Step-by-step explanation:

3(y - 1) = 21

Divide 3 on both sides:

y - 1 = 7

Add 1 to both sides:

y = 8

Multiply by 7 on both sides:

7y = 56

abruzzese [7]

Not sure about the weird echo in the question but I think we're being ask to evaluate

4 - 0.25g + 0.5h

when g=10, h=5

That's

4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 4

Answer: 4
