Answer:
- c) Four times x over four equals four over four; Division Property of Equality
===========================
Given equation and steps to solve it:
- 4(x + 1) = 8
- 4x + 4 = 8
- 4x + 4 - 4 = 8 - 4
- 4x = 4
- 4x/4 = 4/4 <u>This is the missing step</u>
- x = 1
All steps given above including the missing one. As we can see, we divided both sides by 4, so the justification for this step is Division Property of Equality.
Hence, the correct choice is C.
<u>Answer</u>:
[ ( 2 x^2 - x - 5 ) ] / [ ( x + 2 ) ( x - 3 ) ]
option c). is correct.
<u>Step-by-step explanation</u>:
( x + 1 ) / ( x + 2 ) + ( x - 1 ) / ( x - 3 )
= > [ ( x + 1 ) ( x - 3 ) + ( x - 1 ) ( x + 2 ) ] / [ ( x + 2 ) ( x - 3 ) ]
= > [ ( x^2 - 3 x + x - 3 + x^2 + 2 x - x - 2 ) ] / [ ( x + 2 ) ( x - 3 ) ]
= > [ ( 2 x^2 - x - 5 ) ] / [ ( x + 2 ) ( x - 3 ) ]
Hence we get required answer!
