Question

solve the given systems of equations using any method and then choose the correct ordered pair from the given choices: 2x + 3y = 6 5x + 6y = 9

Answer 1

Elimination :
2x + 3y = 6 --->(-2)
5x + 6y = 9
------------
-4x - 6y = - 12 (result of multiplying by -2)
5x + 6y = 9
------------add
x = - 3

now sub -3 in for x in either equation to find y
2x + 3y = 6
2(-3) + 3y = 6
-6 + 3y = 6
3y = 6 + 6
3y = 12
y = 4

check..
5x + 6y = 9
5(-3) + 6(4) = 9
-15 + 24 = 9
9 = 9 (correct)

ordered pair that is a solution is : (-3,4)
