Answer 1

Answer:

12

Step-by-step explanation:

3x + 2 = 50 - x

4x = 48

x=12

Answer 2

Answer:

Given:

3x + 2 = 50 - x

⇒x + 3x + 2 = 50 -x + x (adding x on both sides)

⇒4x + 2 = 50

⇒4x +2 -2 = 50 - 2 (subtracting 2 on both the sides)

⇒4x = 48

⇒4x / 4 = 48 / 4 (dividing both the sides by 4)

⇒x = 12

Answer: 12
