What is the answer of this problem 3sx3s-s=72

3s × 3s -s = 72

(3s × 3s ) -s = 72

9s - s = 72

8s = 72

s = 72/8

s = 9

In this kind of mathematical equations, the use of the BODMAS rule is extremely helpful. Just for an over view:

B stands for Brackets first (parentheses)

O stands for OF (orders i.e. powers, square roots, cube roots etc)

DM stands for Division and Multiplication (start from left to right)

AS stands for Addition and Subtraction (start from left right)

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
