5/10 * 4/9 = 20/90 = 2/9

1/9

Firstly we need to change each fraction into improper fractions. 7/2- 7/3then we need to give each fraction a common denominator. In this case we will use sixths. 21/6 - 14/6. Ans: 7/6

So to start this question, we must multiply out the bracket as follows:2 x (y+3) = 10(2 x y) + (2 x 3) = 102y + 6 = 10Now we take away 6 from both sides of the equation:2y + 6 = 10 (NOW TAKE AWAY 6)2y = 4...

a) y = x/2 - 1 b) y = -2x + 9
