5x+8=-16+7x

Subtract 5x from both sides  and add 16 to both sides

24 = 2x       divide both sides by 2

12 = x

5x+8=-16+7x

so u want to put the x together and the number together in order to find the value of x.

firstly, add 16 to Both sides, this gives : 5x+24=7x

then take away 5x from both sides, this gives : 7x = 24

x= 24/7

x =3.4285.....
