Solve the equation show your work 3x equals 45

x = 15

Step-by-step explanation:

3x / 3 = 45 / 3 x = 15

3x = 45

We have to isolate x. To do that we must bring 3 to the right side of the equation.

How is that done?

Well you need a little bit of magic. Just kidding, you need something close to it. It's called math

Since three is being multiplied by x we have to do the opposite of multiplication to bring it over to the right side and cancel 3 from the left side. The opposite of multiplication is DIVISION so...

3x ÷ 3 = 45 ÷ 3

^^^What you do to one side you do to the other

x = 15

Hope this helped!

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
