Solution

To find the values of (a) and (b) when y = 5, we need to substitute y = 5 into the expressions given for (a) and (b).

(a) (y - 3) x 4 Substitute y = 5 into the expression: = (5 - 3) x 4 = 2 x 4 = 8

So, when y = 5, (a) = 8.

(b) 12 x (y x 4) Substitute y = 5 into the expression: = 12 x (5 x 4) = 12 x 20 = 240

So, when y = 5, (b) = 240.

Therefore, the values of (a) and (b) when y = 5 are 8 and 240 respectively.
