2x + y = 3
-3x + 4y = 1

A.(1, 1)

B.(-1, -1)

C.(1, -1)

D.(-1, 1)

Answer 1

take one equation (you choose which one) and write it as \(y = \dots\).
for example, the first equation gives \(y=3-2x\).

In the second equation replace \(y\) by this expression, you'll be able to find \(x\).

Answer 2

is it C

Answer 3

no

Answer 4

A

Answer 5

yes.

Answer 6

to find \(y\) when you got \(x\) is simple, take one of the two equations, replace x by 1.
