EXAMPLES 1)
Find the value of 5𝑥 + 2 when:
(a) 𝑥
= 2
(b) 𝑥
= 7
(c) 𝑥
= -4
Replace 𝑥 with 2
Replace 𝑥 with 7
Replace 𝑥 with -4 = 5 x 2 + 2 = 5 x 7 + 2 = 5 x -4 + 2 = 10 + 2 = 35 + 2 =
-20 + 2 = 12 = 37 =
-18 2)
Find the value of 4d - 6 when:
(a) d
= 8
(b) d
= 5
(c) d
= 1
Replace d with 8
Replace d with 5
Replace d with 1 = 4 x 8 - 6 = 4 x 5 - 6 = 4 x 1 - 6 = 32 - 6 = 20 - 6 = 4 - 6 = 26 = 14 = -2
