Question 1127708: Okay I have no idea where to post this but, I also have no idea whats going on here.
'Resolve the following equation for B2.' [Note: the numbers are subscript]
A1/B1 = A2/B2
What in the world is this supposed to be? I feel like it's really simple but I'm just missing it. All the numbers are subscript.

Resolve the following equation for B%5B2%5D means solve for B%5B2%5D, isolate B%5B2%5D on one side and everything else on the other side of equation
A%5B1%5D%2FB%5B1%5D+=+A%5B2%5D%2FB%5B2%5D................cross multiply


B%5B2%5D%2AA%5B1%5D+=+A%5B2%5D%2AB%5B1%5D

B%5B2%5D+=+%28A%5B2%5D%2AB%5B1%5D%29%2FA%5B1%5D

It is about  proportions,  that traditionally relate to  Pre-Algebra.


On proportions,  look into the lessons
    - Proportions
    - Using proportions to solve word problems
    - Using proportions to solve word problems in Physics
    - Using proportions to solve Chemistry problems
    - Using proportions to estimate the number of fish in a lake
    - HOW TO algebreze and solve these problems using proportions
    - OVERVIEW of lessons on proportions

These lessons were written specially for you.

Read them and become an expert in this area.

Start from the very first lesson.
