Question

Solve for x. 7(x + 1) = 21

Answer 1

Answer:

x = 2

Explanation:

7( x + 1 ) = 21

Divide both sides by 7

x + 1 = 21 / 7

Divide 21 by 7 to get 3

x + 1 = 3

Subtract 1 from both sides

x = 3 - 1

Subtract 1 from 3 to get 2

x = 2

Answer 2

Answer:

$x = 2$

Explanation:

$7(x + 1) = 21 \\ first \: you \: need \: to \: distribute \\ \\ 7x + 7 = 21 \\ subtract \: 7 \: from \: both \: sides \\ \\ 7x = 14 \\ divide \: both \: sides \: by \: 7 \\ \\ x = 2$
