you must answer all questions above in order to submit.
Step1: Eliminate x, scale equations
Multiply first equation by 3: $3(2x + 3y = 6) \implies 6x + 9y = 18$
Multiply second equation by 2: $2(-3x - 5y = -12) \implies -6x - 10y = -24$
Step2: Add scaled equations
Add the two new equations:
$$(6x + 9y) + (-6x - 10y) = 18 + (-24)$$
Simplify: $-y = -6$
Step3: Solve for y
Multiply both sides by -1: $y = 6$
Step4: Substitute y into first equation
Substitute $y=6$ into $2x + 3y = 6$:
$2x + 3(6) = 6 \implies 2x + 18 = 6$
Step5: Solve for x
Subtract 18, then divide by 2:
$2x = 6 - 18 = -12 \implies x = \frac{-12}{2} = -6$
Filled coefficients for combination:
Top blank: $3$, Bottom blank: $2$
Combined equation: $0x + (-1)y = -6$
Final solution:
$x = -6$, $y = 6$
