Question

3. Solve each equation. Show your work.
a. 2x = 27 - x

Answer 1

2x=27-x - given

3x=27 - add x to both sides

x=9 - divide both sides by 3

Explanation:

Answer 2

`2x=27-x`

Simplify:

`2x=-x+27`

Add x to both sides:

`2x+x=-x+27+x`

`3x=27`

Divide both sides by 3:

`(3x)/(3) =(27)/(3)`

`\fbox{x = 9}`
