(i) x + 7 + 4 (x - 5)
= x + 7 + 4x - 20
= 5x -13
= 5(2) - 13
= 10 - 13
= -3
(ii) 3 (x + 2) + 5x – 7
= 3x + 6 + 5x - 7
= 8x - 1
= 8(2) - 1
= 16 - 1
= 15
(iii) 6x + 5 (x - 2)
= 6x + 5x - 10
= 11x - 10
= 11(2) - 10
= 22 - 10
= 12
(iv) 4(2x – 1) + 3x + 11
= 8x - 4 + 3x + 11
= 11x + 7
= 11(2) + 7
= 22 + 7
= 29
