Question

solve this system of linear equations, separate the x- and y-values with a comma. -14x=-72-19y 9x=87+19y

Answer 1

Answer:

x = - 3, y = - 6

Step-by-step explanation:

Given the 2 equations

- 14x = - 72 - 19y → (1)

9x =  87 + 19y → (2)

Add the 2 equations term by term to eliminate the y- term

- 5x = 15 ( divide both sides by - 5 )

x = - 3

Substitute x = - 3 into either of the 2 equations and evaluate for y

Substituting into (2)

9(- 3) = 87 + 19y

- 27 = 87 + 19y ( subtract 87 from both sides )

- 114 = 19y ( divide both sides by 19 )

- 6 = y

Thus x = - 3, y = - 6
