10 (g+5) = 2 (g+9) how do i solve this

10 (g + 5) = 2 (g + 9) ... distribute thru the parenthesis

10g + 50 = 2g + 18 ... subtract 2g from both sides

10g - 2g + 50 = 2g - 2g + 18 ... simplify

8g + 50 = 18 ... subtract 50 from both sides

8g + 50 - 50 = 18 - 50 ... simplify

8g = - 32 ... divide both sides by 8 ... cancelling the 8 on the left side

g = - 32/8

g = - 4

10 (g+5) = 2 (g+9)

10g + 50 = 2g + 18

10g - 2g = 18 - 50

8g = - 32

g = - 4
