Question

solve using substitution. 4x - y = -11 y = -9 (□, □) save answer

Explanation:

Step1: Substitute $y=-9$ into equation

$4x - (-9) = -11$

Step2: Simplify the left-hand side

$4x + 9 = -11$

Step3: Isolate the $x$-term

$4x = -11 - 9$
$4x = -20$

Step4: Solve for $x$

$x = \frac{-20}{4}$
$x = -5$

Answer:

$(-5, -9)$
