Which ordered pair is a solution of the equation?
3x+3y= -x+5y

a) only (1,2)
b) only (2,4)
c) both (1,2) and (2,4)
d) neither

Respuesta :

nonsibi

First simplify the equation.

3x+3y= -x+5y

4x=2y

2x=y

y=2x

Means that the y value is 2 times the x value.

answer: C but there are more solutions than just (1,2) and (2,4)

The ordered pair that is a solution of the equation is (0, 0). This shows that neither of the given coordinates is correct.

In order to get the ordered pair to the given equation, we will find the x and y-intercept of the given equation as shown:

The y-intercept occurs at the point where x = 0

Given the equation

3x+3y= -x+5y

3x+x = 5y - 3y

4x = 2y

4(0) = 2y

2y=  0

y = 0

Similarly, for x-intercept, it is the point where y = 0

4x = 2y

4x = 0

x = 0

Hence the ordered pair that is a solution of the equation is (0, 0). This shows that neither of the given coordinates is correct.
