Answer:

both methods are correct

Step-by-step explanation:

Given

7(x + 4) = 49 ( divide both sides by 7 )

x + 4 = 7 ( subtract 4 from both sides )

x = 3

---------------------------------------------------------

Given

7(x + 4) = 49 ← distribute parenthesis by 7

7x + 28 = 49 ( subtract 28 from both sides )

7x = 21 ( divide both sides by 7 )

x = 3

As shown both methods are equally valid
