Hello!

Here's how to solve for x.

27=17+2x

Our first step is to subtract 17 from both sides, leaving us with

27-17=17(-17)+2x --- > 10=2x

We then divide both sides by 2 to isolate  x!

10/2=2x/2

10 divided by 2 gives us 5 meaning that x=5

succ0

[tex]x = 5[/tex]
move variable to left side and change its sign
[tex]27 = 17 + 2x[/tex]
to
(you also move the constant to the right and change its sign)
[tex] - 2x = 17 - 27[/tex]
and then calculate the operation in this case you find the difference
[tex] - 2x= 17 - 27 = - 10 \\ - 2x = - 10[/tex]
you then divide both sides of the equation by -2 since the inverse operation of multiplying is division
[tex]x = 5[/tex]
:) hope that helps
