Question

question 8
-7x + y = -19
-2x + 3y = -19
type your answer in the form (x, y)

Explanation:

Step1: Isolate y in first equation

$y = 7x - 19$

Step2: Substitute y into second equation

$-2x + 3(7x - 19) = -19$

Step3: Simplify and solve for x

$-2x + 21x - 57 = -19$
$19x = 38$
$x = 2$

Step4: Substitute x to find y

$y = 7(2) - 19 = 14 - 19 = -5$

Answer:

$(2, -5)$
