Mark as brainliest answer.

Step-by-step explanation:

→ 3x + 7 = 35 - x

→ 3x + x = 35 - 7

→ 4x = 28

→ x = 28/4

→ x = 7

→ RESULT CHECK :

→ Putting x = 7 in 3x+7 = 35 - x

→ If lhs = rhs then value of x is correct.

→ 3(7) + 7 = 35 - 7

→ 21 + 7 = 28

→ 28 = 28

→ Hence , value of x is 7.

→ It is correct.
