I will delete your answer if u give me irreverent solution. ​

Answer 1

Answer:x=21

Step-by-step explanation:

x+x+1+x+2=66

3x+3=66

3(x+1)=66

x+1=66/3

x+1=22

x=22-1

x=21

Hope it helped

Peace.

Answer 2

Solution :-

x + (x + 1) + (x + 2) = 66

=> x + x + 1 + x + 2 = 66

=> 3x + 3 = 66

=> 3x = 66 - 3

=> 3x = 63

=> x = 63/3

=> x = 21

Hence, the value of x will be 21.

Verification :-

Putting the value of x in the equation -

=> 21 + (21 + 1) + (21 + 2) = 66

=> 21 + 22 + 23 = 66

=> 43 + 23 = 66

=> 66 = 66

Hence, verified.

Some algebraic formulas :-

• (a + b)² = a² + b² + 2ab
• (a - b)² = a² + b² - 2ab
• a² - b² = (a + b)(a - b)
