Answer 1

Explanation:

The question is not properly formatted, here is a better format

the expression

`7x+17x-6= (4x+6)`

`x=42`

To verify weather the above is correct we need to solve it our-self

`7x+17x-6= (4x+6)`

Opening up the bracket in the left hand side we have

`7x+17x-6= 4x+6`

Collecting like terms we have

`7x+17x-4x= 6+6`

`24x-4x= 12\\20x= 12`

Divide both side by 20 we have

`x= (12)/(20) = (6)/(5) \\`
