Answer 1

Answer : x = 383/7

Step - by - step Explanation:

7x + 7x +2 - 7x = 385

Slove :

combine like terms :

7x + 7x +2 - 7x = 385

= 7x + 2-2 =385 -2

Subtract 2 from both sides of the equation :

= 7x + 2 -2 =385 -2

Simplify :

= 7x = 385 -2 ( Subtract the numbers)

= 7x = 383 (Subtract the numbers )

Divided both sides of the equation by same term :

= 7x/7 = 383/7

Simplify :

Cancel the terms that are in both the humerator and denominator :

= x = 383/7

Solution :

x = 383/7 ( Answer)
