Substitution

100

Solve the equations if x = 4

6 - x

    6 - 4
= 2

200

Solve the equations if a = 4

6a

   6 x a
= 6 x 4
= 24

300

Solve the equations if a = 3

7a + 4

    7 x 3 + 4
= 21 + 4
= 25

400

Solve the equations if a = 3 and b = 4

b + 5a

(Hint: use BODMAS)

   4 + 5 x 3
= 4 + 20
= 24

500

Solve the equations if a = 6 and b = 7

(b - 3) + 10a

(Hint: use BODMAS)

   (7 - 3) + 10 x 6
= 4 + 10 x 6
= 64
