Q18
- 7/6 = x / (27- 6)
- 6x = 7*21
- x = 147/6
- x = 24.5
Q19
- (x + 5)/15 = (5x + 1)/35
- (x + 5)/3 = (5x + 1)/7
- 7(x + 5) = 3(5x + 1)
- 7x + 35 = 15x + 3
- 15x - 7x = 35 - 3
- 8x = 32
- x = 4
Q21
- (x + 6)/24 = (2x - 2)/27
- (x + 6)/8 = (2x - 2)/9
- 8(2x - 2) = 9(x + 6)
- 16x - 16 = 9x + 54
- 16x - 9x = 54 + 16
- 7x = 70
- x = 10
