Solve the system of equations and choose the correct ordered pair.

3x + 2y = 12
6x + 3y = 21

a. (4, 3)
b. (4, 0)
c. (2, 3)
d. (3, 2)

C.

Step-by-step explanation:

We are going to solve it with substitution, that is, we are going to clear one variable and then replace it in the other equation. Then,

Now, we replace that x value in the equation 6x + 3y = 21:

Finally, we replace the y value found to find x.

So, the solution is (x,y)=(2,3). Then, the answer is C.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
