2Vt - chapter 3 linear equations

Dear students,

Today you get to learn two things. the first thing is how to add and subtract formulas, the second thing is how to solve linear equations.

Read the information on page 109 carefully, here you'll read how to add formulas.

Here another example:

I: y = 2x + 3

II: y = 3x - 1

Given are formulas I and II, the sum formula is the formula of I + II = 2x + 3 + 3x - 1 = 5x + 2

 

1) Now make exercises 28, 29 and 30.

 

Now you'll learn how to solve equations, first watch the video underneath.

After that you can practise solving equations using this link: https://www.mathsisfun.com/algebra/add-subtract-balance.html

And then you should make a few exercises: 36, 37 and 38.
