Question

Solve for g. 10g -8 = 4g + 9g + 10

Answer 1

$10g-8=4g+9g+10\\\\10g-8=(4g+9g)+10\\\\10g-8=13g+10\qquad\text{add 8 to both sides}\\\\10g=13g+18\qquad\text{subtract 13g from both sides}\\\\-3g=18\qquad\text{divide both sides by (-3)}\\\\\boxed{g=-6}$

Answer 2

10g -8 = 4g + 9g + 10

combine like terms

10g -8 =13g +10

subtract 10g from each side

-8 = 3g +10

subtract 10 from each side

-18  = 3g

divide by 3

-6 =g
