Question

7x + 2y = 24\\8x + 2y = 30\type your answer in the form (x, y)

Explanation:

Step1: Subtract the two equations

$(8x + 2y) - (7x + 2y) = 30 - 24$
$8x + 2y - 7x - 2y = 6$
$x = 6$

Step2: Substitute $x=6$ into first equation

$7(6) + 2y = 24$
$42 + 2y = 24$

Step3: Solve for $y$

$2y = 24 - 42$
$2y = -18$
$y = \frac{-18}{2} = -9$

Answer:

$(6, -9)$
