what is 3/4x45 =5x=?

Unfortunately, question is a mystery due to lack of brackets.

Will take a GUESS at
(3/4) (45) = 5x
135 = 20x
x = 135/20
x = 27/4
x = 6¾

PS
Remember to use brackets !!

3/4 * 45 = 5x
5x = 135/4
x = (135/4)/5
x = (135/4)(1/5)
x = 27/4 (6.75)

3/4x45 =5x
3/4x45 x1/5= x
x=27/4
x=6.25

x = 3/4 x 9
= 27 / 4
= 6 3/4

Multiply (3/4) by 45 first. What is three fourths of 45 (or what multiplied by three is 45?) 15. So:

15 = 5x

We need to cancel out the 5, and since the 5 is being multiplied with the x, we must do the reverse operation of multiplication, which is division. So divide on both sides (to keep the equation balanced):

15/5 = 5x/5

The 5 cancels out on the right side, so

15/5 = x
or
x = 3 (because 15/5 = 3)
