Find all solutions of the given system of equations and check your answer graphically. HINT [First eliminate all fractions and decimals; see Example 3.] (If there is no solution, enter NO SOLUTION. If the system is dependent, express your answer in terms of x, where y = y(x).)
3x + 4y = 4
-x - 4/3y = -4/3
(x, y) = (4/3, -4/3)
