Question

How do you solve `4/5(x+5) = 7/8 (3x+23) - 7`?

Answer 1

`x = - 5`

Explanation:

Very nice solution to this problem and I was impressed with the work you did with the fractions. A very common error occurred from line three to line four involving subtraction. Here's the error:
`+161/8 -7`

`+ 161/8 - 56/8`

`+ 105/8` not `- 105/8`

So now the rest of the solution becomes:

`-105/8 + 4 = (21x)/8 - (4x)/5`

`-105/8 +32/8 = (105x)/8 - (32x)/8`

`-73/8 = (73x)/40`

`-5 = x`
