Simplifying:
2n-21=0.25n
We move all terms containing n to the left and all other terms to the right.
+2n-0.25n=+21
We simplify left and right side of the equation.
+1.75n=+21
We divide both sides of the equation by 1.75 to get n.
n=12
The answer is 112892.0654
Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>
