Understanding Two-Step Problems with Reverse PEMBAS

The video tutorial explains how to solve a two-step algebraic problem involving subtraction and multiplication. The instructor demonstrates the reverse PEMBAS method to isolate the variable B. The process involves identifying operations, addressing subtraction by adding, and solving multiplication by dividing, ultimately finding that B equals 12.

What is the main difference in the two-step problem discussed in the video compared to previous examples?

• It includes a minus sign instead of addition.

• It involves a division operation.

• It has more variables.

• It uses a different variable.
