Question

complete the ordered pair so it is a solution of. 3x+2y=36 , which one of these would it be (6,0) (6,9) 6,-9) or (6,6)?

Answer 1

The answer is (6,9)

Explanation:

We simply need to find two numbers that perfectly fits the equation. That is, 2 numbers in which when we substitute the value for x and y works perfectly.

First option is wrong.

3x + 2y = 36

Here, x = 6 and y = 0

Hence, 3(6) + 2(0) = 18 which is wrong.

3rd option is wrong

Here x = 6 and y = -9

3(6) + 2(-9) = 0

Last option is wrong

Here x = 6 and y = 6

3(6) + 2(6) = 18 + 12 = 30.

2nd option is correct

Here x =6 and y = 9

3(6) + 2(9) = 18 + 18 = 36
