Question

3x + 2(x + 2) = 20 - (2x - 5)​

Answer 1

Answer:

Step-by-step explanation:

3x + 2x + 4 = 20 - 2x + 5

5x + 4 = 25 - 2x

5x + 2x = 25-4

7x = 21

x = 21/7

x = 3

Answer 2

3x + 2 ( x + 2 ) = 20 - ( 2x - 5 )

3x + 2x + 4 = 20 - ( 2x - 5 )

5x + 4 = 20 - ( 2x - 5 )

5x + 4 = 20 - 2x - ( - 5 )

5x + 4 = 20 - 2x + 5

5x + 4 = 25 - 2x

5x + 4 + 25 = 25

7x + 4 = 25

7x = 25 - 4

7x = 21

x = 21 / 7
