7x − one over two (8x + 4) = 6 step 1: 7x − 4x − 2 = 6 step 2: 3x − 2 = 6 step 3: 3x − 2 + 2 = 6 step 4: 3x = 6 step 5: x = 2 which step was the error made and why?

Step 3 was made error because 2 is not added to the right side of the equation.

Step-by-step explanation:

Here, the given expression is,

7x − one over two (8x + 4) = 6

⇒

So, the steps which are involved in solving the given equation are as follows,

Step 1 : By distributive property,

Step 2 : Combine like terms,

Step 3 : Adding 2 on both sides,

Step 4 : Combine like terms,

Step 5 : By division property of equality,

Thus, by the above explanation it is clear that step 3 was made error because 2 is not added to the right side of the equation.
