Question

Which ordered pair is a solution to the equation 3x+2y=6 ?

a. (−10,−12)

b. (10, 12)

c. (−10,12)

d. (10,−12)

Answer 1

3(-10)+2(-12)=-54 That's not right!

3(10)+2(12)=54 That's also not right

3(-10)+2(12)=-6 Close but not right

3(10)+2(-12)=6 is the correct answer

Answer 2

You need to use all of them until you find the answer so lets fo this!
a. (-10,-12) x=-10 y=-12
3x+2y=6
3*(-10)+2*(-12)=6
-30-24=6
-54=6
This is incorrect,now we try the othe options
b.(10,12) x=10 y=12
3x+2y=6
3*10+2*12=6
30+24=6
54=6
This is incorrect then we try the other option
c. (-10,12) x=-10 y=12
3x+2y=6
3*(-10)+2*12=6
-30+24=6
6=6
And this is the correct answer. So the answer is c. (-10,12)
