Answer:
Solve for X ( The question I did was an example )
Step-by-step explanation:
To solve and equation like 2x+9=30 you will have to isolate the number with a variable. You need to subtract 9 on both sides for that to happen.
2x=21
Now the next step is to divide. You have to divide to get the answer.
x=21/2
x= 10.5
13 + (-12) - (-5)
13 - 12 + 5
1 + 5
= 6.
