Question

Find y if 1030404(3y+36) = 1030403(3y+36).

Answer 1

For this case we have the following equation:

`1,030,404 (3y + 36) = 1,030,403 (3y + 36)`

We apply distributive property to the terms within parentheses:

`3,091,212y + 37,094,544 = 3,091,209y + 37,094,508`

We subtract
`3,091,209`and on both sides of the equation:

`3,091,212y-3,091,209y + 37,094,544 = 37,094,508\\3y + 37,094,544 = 37,094,508`

We subtract
`37,094,544`on both sides of the equation:

`3y = 37,094,508-37,094,544\\3y = -36`

We divide by 3 on both sides of the equation:

`y = - \frac {36} {3}\\y = -12`

Answer:

`y = -12`
