A. When you equalize two equations, geometrically you are trying to find the intersection point of them, i.e. find the common point of them. So the x coordinate of the intersection point is basically the solution.
B. You can simply plug in numbers from -3 to 3 and list the values by yourself.
C. Graphically, draw each equation, and find the x coordinate of the intersection point.
FYI, the solution is x = 1/3

Answer:

Option D is the correct option.
Step-by-step explanation:

When there is a ( + ) in front of an expression in parentheses , there is no need to change the sign.
That means, the expression remains the same.
Just remove the unnecessary parentheses

1) you would need to turn both fractions so they have a common denominator, that would be 2 2/4 and 3/4
2) then subtract : 2 2/4 - 3/4, and you would subtract numerators and the whole number, but you keep the denominator the same. However, you cannot subtract 2 and 3 in this case, so you need to change 2 2/4 to 1 5/4 (they are still equivalent)
3) 1 5/4 - 3/4 = 1 2/4, which simplified version is 1 1/2
Therefore, the answer is 1 and 1/2
