12 is a solution of the equation 4x – 5 = 3x + 10. State true or false

Solution:

Let’s solve the equation 4x – 5 = 3x + 10

4x – 3x = 10 + 5

x = 15

Hence 15 is a solution of the equation 4x – 5 = 3x + 10.

Thus, 12 is a solution of the equation 4x – 5 = 3x + 10. False.

✦ Try This: 8 is a solution of the equation 7x – 19 = 3x + 17. State true or false

Let’s solve the equation 7x – 19 = 3x + 17

7x – 3x = 17 + 19

4x = 36

x = 36/4

x = 9

Hence 9 is a solution of the equation 7x – 19 = 3x + 17.

Thus, 8 is a solution of the equation 7x – 19 = 3x + 17. False.
