Question

solve the system of equations:$12x - 5y = -20$$y = x + 4$$x = \square$$y = \square$

Explanation:

Step1: Substitute $y=x+4$ into first equation

$12x - 5(x + 4) = -20$

Step2: Expand and simplify the equation

$12x - 5x - 20 = -20$
$7x - 20 = -20$

Step3: Solve for $x$

$7x = -20 + 20$
$7x = 0$
$x = 0$

Step4: Substitute $x=0$ into $y=x+4$

$y = 0 + 4$

Answer:

$x = 0$
$y = 4$
