Question

Find the values of x in the following equation:
|10x + -9| = 59

Answer 1

The inside of the absolute value can equal 59 or what other number?

Remember when you take the absolute value of something, it gives you the numerical value of that number or you can think of it as the distance from zero on a number line.

Answer 2

In this case that means that whatever is inside the absolute value can equal 59 OR -59, so you need to set up two separate equations to show this.

Answer 3

10x + (-9) = 59 10x + (-9) = -59

Solve both of those for x and those are your answers.

Answer 4

i have no idead

Answer 5

Those are just equations.

You can solve equations by isolating or getting the x by itself. You can think of how to do this by reversing the operations that are happening to x.

In the first equation you are taking 10 times x - 9.

What is the opposite of subtracting 9?

Answer 6

mkuehn, math is only looking for ansewrs, he was here yesterday asking about coordinates..

Answer 7

yea well we are against that

Answer 8

I am giving him the answer. He just has to work it out himself. :)

Answer 9

as bahrom just taught me xD

Answer 10

Unless this is like rocket science stuff

Answer 11

If it were related rates or optimization or some linear algebra i would've provided the solution and the answer, cuz those can be complicated

Answer 12

or sin or anything like that, this is basic algebra that you're going to need later bud, sorry to say it.

Answer 13

medal please
