Not a real number because a negative number is imaginary
Answer: Assuming by similar it means proportional, I'd suppose D.
The answer is 5 because 5(x) plus two equals seven and 5(x) subtracted by 2 equals 3
7x = 1 + 2x
1. Subtract 2x from both sides
5x = 1
2. Divide it all by 5
<em><u>x = 1/5</u></em>
<em><u>SO X EQUALS TO 1/5.</u></em>
