Answer:

the number is 3

Step-by-step explanation:

Perhaps you'd like to find the number.

If n represents the number, we can write the relationship as ...

3n -1 = n +5

Adding 1-n to both sides gives ...

2n = 6

n = 3 . . . . divide by 2

The number is 3.

_____

Check

The product of the number and 3 is 9. One less is 8. That is 5 more than the number itself: 8 = 3 + 5.

Use the order of operations to simplify 5*3 to the second power-15/5

ASHA 777 [7]

Assuming the question reads:

$5 \cdot 3^2 - 15 \div 5$

The order of operations is as follows:

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

There are no parentheses in the equation.

There is an exponent in the equation. Solve this term first:

$3^2 = 9$

The equation should now read:

$5 \cdot 9 - 15 \div 5$

There are two multiplication/division operations in the equation. Solve them individually:

$5 \cdot 9 = 45$

$15 \div 5 = 3$

The equation should now read:

$45 - 3$

There is one subtraction operation. Solve this term for your answer:

$45 - 3 = \boxed{42}$
