Question

Write which operation must be done on both the side (x+7=12 (2) x-6 = 10
(3) 15x = 60​

Answer 1

Answer:

Given:

(1) x+7=12

(2) x-6 = 10

(3) 15x = 60

To find:

Find the value of x

Solution:

(1) x + 7 = 12

5 + 7 = 12

so, x = 5

(2) x - 6 = 10

16 - 6 = 10

so, x = 16

(3) 15x = 60

15 × x = 60

15 × 4 = 60

so, x = 4

Therefore:

1) x = 5

2) x = 16

3) x = 4

Answer 2

Answer:

1)x+7=12

x=12-7

x=5

2) x-6=10

x=10+6

x=16

3)15x = 60

x = 60/15

x = 4
