Answer:
x = 7.5
Step-by-step explanation:
So the equation looks like this:
2X -3 =12
So we are first going to get rid of -3 by adding 3 to both sides of the equal sign:
2X -3 = 12
+ 3 +3
SO the equation looks like this now:
2x = 15
Now we are going to segregate the variable x by dividing 2x and 15 by 2:
2x/2 = 15/2
x = 7.5
So in order to check our work we are going to substitute 7.5 where the x variable is in the equation:
2X -3 =12 or 2(7.5) - 3 = 12
2(7.5) - 3 = 12
15 - 3 = 12
12 = 12
So our answer to what the variable x equals is 7.5.
I hope this helps you!!
