If Jaalan takes the number of marbles he has and multiplies it by 5 and then subtracts 10, he gets 275. Write an equation and solve to see how many marbles Jaalan has.

Answer 1

Let's assume the number of marbles Jaalan has is "x".

According to the given information, we can write the equation as follows:

5x - 10 = 275

To solve for x, let's isolate the variable on one side of the equation:

Adding 10 to both sides:
5x = 275 + 10
5x = 285

Dividing both sides by 5:
x = 285/5
x = 57

Therefore, Jaalan has 57 marbles.
