A system of equations is shown. x−y=−8
x+y=4
Which is a method that can be used to eliminate a variable? Select all that apply.

a)Add the terms in the bottom equation to the terms in the top equation to eliminate y

b)Multiply the terms in the bottom equation by 2 and add the resulting terms in the top equation to the terms in the top equation to eliminate x

c)Subtract the terms in the top equation from the terms in the bottom equation to eliminate x

d)Multiply the terms in the bottom equation by 4 and subtract the resulting terms in the bottom equation from the terms in the top equation to eliminate y

step-by-step explanation:

this woman was an important writer and propagandist during the american revolution. she was a member of the committee of correspondence (in fact the committee was formed in her home) and was an advisor to many of the revolutionary leaders, including george washington and john adams. who was this revolutionary woman?

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
