Answer:
x = 5
Step-by-step explanation:
20(20-x)=300
1. Divide both sides by 20.
20(20-x)/20 = 300/20
2. Simplify.
20-x=15
3. Subtract 20 from both sides.
20-x-29=15-20
4. Simplify.
-x=-5
5. Divide both sides by -1.
-x/-1 = -5/-1
6. Simplify.
x=5
To solve this we must isolate x which involves having the variables on one side and the numbers on the other.
First add 2m to both sides
<em>3m+7/2=-2m+5/2</em>
<em>5m+7/2=5/2</em>
Then we subtract 7/2 from both sides
<em>5m+7/2=5/2</em>
<em>5m=-1</em>
Finally we divide both sides by 5
<em>5m/5=-1/5</em>
<em>Our final answer is -1/5</em>
<em>So the answer is B</em>
Hope this helps!
