Question 239793: hi sir. how we can make equation from word problems

You can put this solution on YOUR website! Word problems tend to be tricky and it takes a while to get used to them, but here are a few hints.
.
If the problem tells you there are several consecutive integers, write the following on your notebook:
x = integer
x+1 = consecutive integer
x+2 = next consecutive integer ... continue for as many consecutive #s you're given in the problem.
.
Be careful, though. Some problems want you to look for several consecutive EVEN integers. In which case, you'd write on your notebook:
x = integer
x+2 = consecutive even integer
x+4 = next consecutive even integer ... again, continue for as manyas you need.
.
The problems start telling you how you add, substract, multiply, or divide (+-*/) two of the integers.
.
Then it probably also gives you another (+-*/) wording.
.
The words "equal" and "is" mean the symbol =
.
The word "least integer" would refer to the value of x. Whereas the "greatest" or "largest" integer would be the highest value of x you noted on your notebook (ex. x+4).
.
When you (+ - * or /) your integers, remember to write them as stated above. For instance, if the problem tells you "the third integer is twenty seven more than 3 times the least integer"... you would write: (x+4)+27=3(x).
.
Once you get the equation, work out the algebra and solve for x. This gives you the first integer. Then it would be very easy to figure out the rest of the integers.
.
Always check your answers by pluggin the value of x in the original equation to ensure both sides of the equation are equal to each other. If they are not, then you did something wrong.
.
Good luck!
