Question
) (y - 3) x 4(b) 12 x (y x 4)Find the value of (a) and (b) when y = 5.(a) , (b)
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.
