1. Targeting Grade C
Starter - Tarsia

2. 1 2 3 4 5 6 7 8 9 10 What can we do to start – try 5 5y + 6 = 21
What’s your level (1 – 10) 1 2 3 4 5 6 7 8 9 10
3x – 5 = 10
5y + 6 = 21
2(x + 4) = 12
5(y – 3) = 5
8x + 12 = 20
4x +5 = 2x + 9
3y – 2 = 2y + 8
5t – 8 = t + 16
15x + 6 = 7x - 2
20y – 16 = 18y -10

3. E/D Solve the following
(i) x + 5 = 16
(ii) 3x + 4 = 19
(b) 6y + 9 = 45
D/C
Multiply out the brackets first:
2(x + 3) = 16
(b) 3(2x – 3) = 9 C
(i) 9x – 14 = 4x + 11
(ii) 20y – 16 = 18y - 10
