How to do 6b - 8 - 5b=
zhuklara [117]

b = 8


Since 6b and 5b have the same variables, you can subtract them both. 1b, but I'd perfer just b. Then, swap the -8 to the other side. It makes it positive. So it's b = 8.

Given:
anygoal [31]
First off, remember PEMDAS. Then replace the variables with the values.
3(2x3)^2
First distribute the exponent to the value on the inside.
3(4x9)

Then multiply the 4 and 9.
3(36)

After that just distribute the 3.
3x36 = 108.

I've been stuck on this question for a while now, I need help!
MaRussiya [10]
In order to solve it you must make each component negative. Multiply them by negative one!

M < 2

Now which numbers would satisfy it? M is less than two... so, m could be one, or any negative number, yeah?

Multiply by negative one. - M and -2 are what you have. If it were one... negative one is less than negative two. Turns out M is less than two.

M < 6

M is less than six. It could be 1, 2, 3, 4, or 5.

-M and -6

Is negative 3 less than -6? All of the numbers are! So, m is actually less than 6
