Problem:
10-7(x+2)=21
Please help me out if possible!

Answer 1

Answer:

$x = - \frac{25}{7} .$

Step-by-step explanation:

$10 - 7(x + 2) = 21 \\ \\ 10 - 7x - 14 = 21 \\ \\ - 7x - 4 = 21 \\ \\ - 7x = 25 \\ \\ x = - \frac{25}{7} .$

Answer 2

Step-by-step explanation:

10-7(x+2)=21

$10 - 7x + 14 = 21 \\ - 7x + 24 = 21 \\ - 7x = 24 - 21 \\ - 7x = 3 \\ x = \frac{3}{ 7}$
