Answer:
[tex] \huge{ \bold{ \boxed{ \tt{g = 3.5}}}}[/tex]
Explanation:
[tex] \text{ - 5 + 7g = 3g + 9}[/tex]
[tex] \text{Step \: 1 : \: Move \: 3g \: to \: left \: hand \: side \: and \: change \: its \: sign.}[/tex]
[tex] \text{ ➸ \: - 5 + 7g - 3g = 9}[/tex]
[tex] \text{ Step \: 2 : Move \: 5 \: to \: right \: hand \: side \: and \: change \: its \: sign.}[/tex]
[tex] \text{➸ \: 7g - 3g = 9 + 5}[/tex]
[tex] \text{Step \: 3 : Subtract \: 3g \: from \: 7g}[/tex]
[tex] \text{➸ \: 4g = 9 + 5}[/tex]
[tex] \text{Step \: 4 : Add \: the \: numbers \: : 9 \: and \: 5}[/tex]
[tex] \text{➸ \: 4g = 14}[/tex]
[tex] \text{Step \: 5 : Divide \: both \: sides \: by \: 4}[/tex]
[tex] \text{➸ \: 4g / 4 \: = \: 14 /4}[/tex]
[tex] \text{➸ \: g \: = \: 3.5}[/tex]
[tex] \text{Hope \: I \: helped!}[/tex]
