In the equation, 7 (3a+12)=168 , what are some of the steps that should be taken to solve for x? select all that apply. subtract 84 from both sides of the equation. divide both sides of the equation by 3. distribute the 7 among the terms inside the parentheses. divide both sides of the equation by 21.

7(3a + 12) = 168 ← ( divide both sides by 7 )

3a + 12 = 24 ← ( subtract 12 from both sides )

3a = 12 ← ( divide both sides by 3 )

a = 4

OR

distribute the parenthesis by 7

21a + 84 = 168 ← ( subtract 84 from both sides )

21a = 84 ← ( divide both sides by 21 )

a = 4
