Answer 1

Step-by-step 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

$x= \frac{12}{20} = \frac{6}{5}$
