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] ...

Math is one of the hardest subjects in school, which is why owning a graphing calculator seems like a necessity for students. But what if you could use your smartphone to solve equations by pointing ...
