Question

1. Solve the equations by trial and error method :
(i) x + 7 = 11
(ii) 14 - x = 6
(iii) 4x = 36
(iv) 3x = 15/6
(v) 7x = 1
(vi) 5x/2 = 50
​

Answer 1

Answer:

1. x+7=11

x=11-7

x=4

2. 14-x=6

x=6+14

x=20

3. 4x= 36

x = 36/4

x=9

4. 3x= 15/6

x = 15/6×3

x= 45/6

5. 7x=1

x= 1/7

6.5x/2=50

5x=100

x=20.
