Question asks if each expression equals
E = (10+x) / (y-3)
[note that the parentheses are VERY significant. All fractions transcribed on a single line must have parentheses around the numerator AND denominator]
1. (10+x)/y - 3 = (10+x)/y - 3y/y = ((10+x)+3y) / y
since both denominator and numerator are not equivalent to E, the answer is negative.
2. (10+x) / (y-3) is exactly equivalent to E, so the answer is affirmative.
3. 10+x/y -3 = (10y + x -3y)/y
since both denominator and numerator are not equivalent to E, the answer is negative.
4. (10+x-3)/y
since both denominator and numerator are not equivalent to E, the answer is negative.
