Make sure you are confident in calculating with negative numbers, which is a skill often needed to solve equations. To solve the equation, do the inverse operation. The inverse of multiplying by 12 is ...

⇒x = 7 + 2 (by transposing 2 to R.H.S.) ⇒y = 10 − 3 (by transposing 3 to R.H.S.) ⇒y= 7. 1.6 = y/1.5 ⇒1.6 x 1.5 = (y/1.5) x 1.5 [On multiplying both sides by 1.5] ...

The use of concrete models for teaching students how to solve equations is often debated in scientific literature. This article aims to examine the balance model and to identify the issues that divide ...
