Evaluate each system below with the point (1, 2/3). Select the system or systems which have the point (1, 2/3) as a solution:
a. 3x + 3y = 1 and y = 1
b. 2x + 6y = 2 and y = 2/3
c. x + y = 5/3 and x  y = 1/3
d. 3y = 2x and 2y = 3x
e. x + 3y = 2 and x = 1

Best ResponseYou've already chosen the best response.0you need to plug the value of x or y from the point (1,2/3) into each equation. in choice c. , if you plug the value of x from the point, which is 1, the equation will be : (1) + y = 5/3 > y= 5/3 + 1 > y= 2/3. and (1)  y = 1/3 > y = 1+ 1/3 > y = 2/3 that means both equations from choice c have the point (1, 2/3) therefore choice c is the right answer

Best ResponseYou've already chosen the best response.0choice a, b and e can't be right because in choice a ,the equation y= 1 doesnt have any value of x in choice b, the equation y = 2/3 also doesnt have any value of x in choice e, the equation x =1 doesnt have any value of y
