Answer:
<u>12 years</u>
Step-by-step explanation:
Let Kishor's present age be denoted by x.
According to the question :
- He will 3 times as old as he was 4 years ago after 12 years
Therefore, the equation is :
Solving :
- x + 12 = 3x - 12
- 3x - x = 12 + 12
- 2x = 24
- x = <u>12 years</u>
<u></u>
Hence, Kishor's present age is <u>12 years</u>.
Answer:
w=15
Step-by-step explanation:
-24=-3w+21
We move all terms to the left:
-24-(-3w+21)=0
We get rid of parentheses
3w-21-24=0
We add all the numbers together, and all the variables
3w-45=0
We move all terms containing w to the left, all other terms to the right
3w=45
w=45/3
w=15
Answer:
Step-by-step explanation:a/
