Answer:

Improper fraction form: y = 36/5

Decimal form: y = 7.2

Mixed number form: y = 7 1/5

Step-by-step explanation:

First distribute 25 among everything inside the 1st parentheses to get 125y - 250 in its place.

Now you have 7 + 125y - 250 = 45 (y+5) + 15y

Next distribute the 45 among everything in the 2nd parentheses to get 45y + 225 + 15y in its place.

Now, altogether you have 7 + 125y - 250 = 45y + 225 + 15y

Now we combine the like terms:

7 + (-250) = 7 - 250 = -243

45y + 15y = 60y

-243 + 125y = 60y + 225

Now we isolate for y:

Add 243 to 225, to get 468, and then subtract 60y from 125y to get 65y.

Now we have 65y = 468, so finally we divide 65 on both sides to get y = 468/65, and we can simplify this fraction to 36/5.

As a decimal: 7.2

As a mixed number: 7 1/5

Hope this helps you :)
