Question

How to solve this please? 2x - 5 = 4

Answer 1

Hey there, below you will find the work and answer to your question.

2x-5=4

First lets get the 2x by itself so we have to add 5 on both sides.
2x-5=4
   +5 +5
2x=9
Now we need to get the X by itself so divide each side by 2
$\frac{2x}{2} = \frac{9}{2}$
Now we are left with the following
X=$\frac{9}{2}$
We must simplfy the fraction
2 will go into 9 four times with 1 left over. So the mixed fraction answer would be:
x=$4 \frac{1}{2}$
As a decimal you would just divide 9 and 2
x=4.5

Hope this helped!

Answer 2

$2x - 5 = 4 \\ 2x = 4 + 5 \\ 2x = 9 \\ x = \dfrac{9}{2} \\ x = 4 \dfrac{1}{2}$

Or in decimal form, 4.5

Hope this helps. - M
