Chelsea shows her work in finding the solution to 4x−5=2+3(x−3) 4 x 5 2 3 ( x 3 ) . after checking her answer in the original equation, she found that it did not work. where did she make a mistake?

The mistake made by Chelsea was that she forgot to multiply the numbers in the bracket.

Order of Operations in Mathematics follow this following rule :

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem !
