Answer:
The step 4 is not what he should have done. But the wrong is step 5, because if he added -2x both sides, it would give the following equation:
and not 
Note that in step 4 he should have added 2x and not -2x to both sides, but we still have the equality. The problem is that step 5 is totally wrong.
I don't know what answer is expected to this question, but I would mark step 5, because this is mathematically wrong.
Solving the equation
Using distribution
Add 
both sides
Add 12 both sides
Divide both sides by 5

Answer:
39785
Step-by-step explanation:
or,40596×2÷100=811
or,40596-811=39785
To find what percentage one number is of another; divide the first number by the other number and multiply by 100 !
p = ( 6 / 76 )× 100 ;
p = 600 / 76 ;
p = 7.89 ≈ 8 ;
p% = 8% ;
Answer:
So Equation ( 1 ) is NOT Equivalent to Equation ( 2 )
Step-by-step explanation:
Given:
..............Equation ( 1 )
................Equation ( 2 )
To Find:
Whether Equation ( 1 ) is Equivalent to Equation ( 2 )
Support your answer by evaluating the expression for t = 2.
Solution:
For t=2 Equation ( 1 ) we get
For t=2 Equation ( 2 ) we get
From above we get two different values
So Equation ( 1 ) is NOT Equivalent to Equation ( 2 )
