Question

How do you solve `2+ 2g = 8`?

Answer 1

`g=3`

Explanation:

`2+2g-2=8-2`
`2g=6`
`2g/2=6/2`
`g=3`

Answer 2

Subtract 2 from both sides
then divide both sides by 2
to get `g=3`

Explanation:

`2+2g=8`

`2+2gcolor(red)(-2)=8color(red)(-2)`
`rArr 2g=6`

`(2g)color(red)(div2)=6color(red)(div2)`
`rArr g=3`

Answer 3

`g=3`

Explanation:

`"isolate "2g" on the left side of the equation by subtracting"`
`"2 from both sides"`

`cancel(2)cancel(-2)+2g=8-2`

`2g=6`

`"divide both sides by 2"`

`(cancel(2) g)/cancel(2)=6/2rArrg=3`

`color(blue)"As a check"`

Substitute this value into the left side of the equation and if equal to the right side then it is the solution.

`2+(2xx3)=2+6=8=" right side"`

`g=3" is the solution"`
