Question

How do you solve `2( 2e - 8) + 5e = 29`?

Answer 1

`e = 5`

Explanation:

First expand the brackets:

`2(2e-8) + 5e = 29`
`4e -16 +5e = 29`

Then collect all of the like terms together. In this case I add the e's together on the left hand side and add 16 to both sides.

`4e -16 +5e = 29`

`4e + 5e - 16 + 16 = 29 + 16`
`9e = 45`

Then solve for e by diving 45 by 9

`e = 45 / 9`
`e = 5`

Answer 2

`e=5`

Refer to the explanation for the process.

Explanation:

Solve:

`2(2e-8)+5e=29`

Expand the left side.

`4e-16+5e=29`

Add `16` to both sides.

`4e+5e=29+16`

Simplify.

`9e=45`

Divide both sides by `9`.

`e=45/9`

Simplify.

`e=5`
