Questions Of The Week From Spring 2018

Algebra Question 4

We are having a few weeks of algebra questions. Here's our fourth one - solving a formula with unknowns on both sides


Algebra Question 3

This was our third one - changing the subject of a formula.

Step 1: Take the 2y away from both sides:  3x = 5 - 2y

Step 2: Divide both sides by 3:   x = (5 - 2y)/3


Algebra Question 2

Here was our second one - substitution into an algebraic expression.

‚ÄčSolution:
(5 x 5) + (3 x -2)
= 25 + (-6)
= 25 - 6 = 19


Algebra Question 1

Here was our first algebra question - solving an algebraic equation to find x.


Solution:
Step 1: Add 10 to both sides to get 3x = 15
Step 2: Divide both sides by 3 to get x = 5
