Write an equation for the following:
If two-thirds of a number is added to 4 times the number, then the result is 20.
Let the number be x.
Now, 23 of x is 23x and 4times of xis 4x.
Hence, the required equation is 23x+4x=20.
If one-third of the number is subtracted from 5 times a number, then the result is 14.
12is added to a number x.The sum is multiplied by 4.The result is 18.
Write an equation for each of the following statements :
3 times a number x added to 5 times another numbery is equal to 48.
17 is added to a number x. The sum is divided by 5. The result is 6.
If one-tenth of a number x is subtracted from seven times the number, then the result is 138.
