Question

Solve the following equations using trial and error method. X+5=13, 2x=16 , 2x=16, 3x+7=16, 4x /3 =4 , 5x+12=17, 2x+5=15 for class 6th.

Answer 1

Answer:

1. 8

2.and 3. 8

4. 3

5. 3

6. 1

7. 5

Step-by-step explanation:

1. x+5=13

or, x =13-5=8

2. 2x=16

or , x =16/2=8

4. 3x+7=16

or, 3x = 16-7=9

or, x = 9/3=3

5. 4x /3 =4

or, 4x=4×3=12

or, x=12/4=3

6. 5x+12=17

or, 5x=17-12=5

or, x=5/5=1

7. 2x+5=15

or,2x = 15-5=10

or, x=10/2=5
