Distribute 1/2 to <span>(n – 4):
</span>


<span>
Subtract (2n + 3):
</span>

<span>
Your equation should now look like this:
</span>

<span>
Combine like terms on both sides:
</span>



<span>
Subtract 1/2n from both sides:
</span>

<span>
Divide both sides by -5/2 to get n by itself:
</span>

<span>
The value of n is
2.</span>

Answer:
3
Step-by-step explanation:
Let x represent the number. The problem statement tells you ...
2/3(3x +6) = 10
2x +4 = 10 . . . . . . use the distributive property
x +2 = 5 . . . . . . . . divide by 2
x = 3 . . . . . . . . . . .subtract 3
The number is 3.

<em>Comment on the solution</em>
The above shows an "alternative" solution method. The more usual way this might be done is ...
2(3x +6) = 30 . . . . . multiply by 3 to clear fractions
6x +12 = 30 . . . . . . . eliminate parentheses
6x = 18 . . . . . . . . . . . subtract 12
x = 3 . . . . . . . . . . . . divide by 6
Answer:
5
Step-by-step explanation:
because ?*9=45
45÷9=5
How to solve this: (in case you need it)
4n-18=52
4n-18+18=52+18
4n=70
4n/4=70/4
n=35/2
