Question

Solve the equation and verify the answer in each case:
3x + 5 + 2x + 6 + x = 4x + 21.
​

Answer 1

Step-by-step explanation:

3x+5+2x+6=4x+21

5x+11=4x+21

1x=10

x=10/1

x=10

Answer 2

Answer:

x = 5

Step-by-step explanation:

$3x + 5 + 2x + 6 + x = 4x + 21 \\ 3 x + 2x + x - 4x = 21 - 5 - 6 \\ 2x = 10 \\ x = \frac{10}{2} \\ x = 5$
