Question

How do i find y in this equation: 5y/4 = 10

Answer 1

y=8

Explanation:

We move all terms to the left:

5y/4-(10)=0

We multiply all the terms by the denominator

5y-10*4=0

We add all the numbers together, and all the variables

5y-40=0

We move all terms containing y to the left, all other terms to the right

5y=40

y=40/5

Answer 2

y = 8

Explanation:

`(5y)/(4) = 10`

`(4)/(5) * (5y)/(4) = (4)/(5) * 10`

`(1)/(5) * 5y = (4)/(5) * 10`

`y = (4)/(5) * 10`

`y = 4 * 2`

`\boxed{\green{y = 8}}`
