Solve the system by graphing -3x-2y=-7 and 3x-y=10

it would open into a square depending on the type of envelope i’m not sure about the second part

could you provide figure.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

slope intercept form is y = mx + b
