Question

-6x+3y=-39 -6x-3y=-21 solve the system of equations

Answer 1

The answer is the one on top

Answer 2

Answer:

x=5,y=-3

Step-by-step explanation:

$\left \{ {{-6x+3y=-39} \atop {-6x-3y=-21}} \right. \\-12x=-60\\12x=60\\x=\frac{60}{12} \\x=5$

$-6(5)+3y=-39\\-30+3y=-39\\3y=-39+30\\3y=-9\\y=-\frac{9}{3} \\y=-3$
