What are the possible steps involved in solving the equation shown? check all that apply. 3.5 + 1.2(6.3 – 7x) = 9.38 add 3.5 and 1.2. distribute 1.2 to 6.3 and –7x . combine 6.3 and –7x . combine 3.5 and 7.56. subtract 11.06 from both sides. divide both sides by 9.38.

Answer : 2 ,4 and 5 are the possible steps involved in solving the equation .

Given equation:

1)Add 3.5 and 1.2. , we cannot do that as according to the BODMAS , bracket must be solved first.

2) Distribute 1.2 to 6.3 and –7x , it can be true by using distributive property we can distribute 1.2 to both the numbers in the bracket.

3) Combine 6.3 and –7x ,we cannot combine unlike terms, so it is not possible.

4)Combine 3.5 and 7.56.

After 2) step we get 3.5+7.56-8.4x=9.38,here we can combine 3.5 and 7.56 {both are constants] to get,

11.06-8.4x=9.38

5) Subtract 11.06 from both sides,we get

11.06-8.4x-11.06=9.38-11.06

⇒-8.4x= -1.68 after that , divide -8.4 both sides ro remove it from the left side, Thus we get x=0.2

So 6) Divide both sides by 9.38. is also not possible.
