Question

How do you solve `-98= - 7x - 8( 1+ x )`?

Answer 1

x = 6

Explanation:

First, write out the problem.

`-98 = -7x - 8( 1 + x )`

Before you do anything else, make the subtraction signs addition signs, followed by a subtraction symbol.
Then, use the distributive property and multiply:

`-8 xx 1, and -8 xx x`.

After all that, it should looks like this:

`-98 = -7x + (-8) + (-8x)`

Then, combine like terms `-7x and -8x`, giving you the following:

`-98 = -15x + (-8)`

Now, you add eight to both sides `(-98 and -8)`.

You will now have this:

`-90 = -15x`

Finally, divide `-90 and -15` by`-15`, and you will end up with:

`6 = x`, or

`x = 6.`
