Question

Which of the following ordered pairs is the solution to the system of linear equations?
x plus y equals fourteen, Two x plus y equals twenty-four

Answer 1

Use the substitution method.

y = 3x - 1 into x + 2y = 12 =
x + 2(3x - 1) = 12
x + 6x - 2 = 12 (distribute 2 into 3x - 1)
7x - 2 = 12 (combine like terms)
7x = 14 (add 2 to both sides)
x = 2 (divide by 7)

Now that you have determined x --

y = 3x - 1
y = 3(2) - 1
y = 6 - 1
y = 5

So, your ordered pair is (2, 5) answer from yahoo answers

Answer 2

oh my gosh thank you

Answer 3

but i just looked at the multiple choice and their is no ordered pairs with those numbers.

Answer 4

your welcome my pleasure

Answer 5

ok just ignore the pair
