I am reviewing Algebra for my GRE test. Here is one inequality problem that I do not understand...
I will provide the equation, the choices of answers, and their answer. I want to know HOW they solved it! Thank you!
the letter x represents variable "x"
Equation writing in words: If 3x PLUS 4 is GREATER THAN Seventeen, 3x PLUS 7 is GREATER THAN
If 3x + 4 > 17, 3x + 7 >
Choices for Answers:
3x + 7 = (3x + 4) + 3 > 17 + 3 = 20
I appreciate any feedback for this type of inequality problem!
I reviewed what you posted, and looked back at the problem...NOW it makes sense!!
I see now, they (in the original equation) gave a partial answer.
It was a matter of knowing what step to do on the left side, thus you have to do the step on the right side!!
