Question

8x - 3y = 19
x = -1
(□, □)
submit

Explanation:

Step1: Substitute \( x = -1 \) into the equation

We have the equation \( 8x - 3y = 19 \) and \( x = -1 \). Substitute \( x=-1 \) into the equation:
\( 8\times(-1)-3y = 19 \)

Step2: Simplify and solve for \( y \)

First, calculate \( 8\times(-1)=-8 \), so the equation becomes:
\( -8 - 3y = 19 \)
Add 8 to both sides:
\( -3y = 19 + 8 \)
\( -3y = 27 \)
Divide both sides by -3:
\( y=\frac{27}{-3}=-9 \)

Answer:

\((-1, -9)\)
