5less than three times a number is 10 what is the solution?

Let n = the unknown number.

"less than" tells you subtract.

"three times" tells you multiply the number by 3.

3n + 5 = 10

Add 5 from both sides to get the variable on one side and the constant on the other.

3n = 10 + 5

3n = 15

Divide both sides by 3 to isolate the variable:

n = 5

Let us say the number is x.

Now let us make an expression for it.

Step 1:

three times the number means multiply x by 3 so 3x.

Step 2:

5 less than three times the number

so subtracting 5 from 3x we have 3x-5

Step 3:

Making equation, "is" stands for equal to 10 here, so we have

Step 4:

Now solving the equation

Since 5 is in subtraction on left so adding it on right side

dividing both sides by 3
