Question

Solve, using linear combination.

3x – y = 4
2x + y = 6





(0, –4)



(–1, –7)


(2, 2)


(3, 0)

Answer 1

Solve both equations for y and set the results equal to each other to solve for x. When you get what x is, plug the answer back into one of the equations in terms of y and you will get y.

Answer 3

Still need help?

Answer 4

yes

Answer 5

\[5x = 10 \]
\[5 \times ? = 10\]

4 + y = 6
\[4 + ? = 6\]

Can you answer the ? @WildQueen

Answer 6

I DONT GET IT

Answer 7

5 multiplied by what number equals 10 @WildQueen

Answer 8

ok is it c

Answer 9

Yes the answer is C because: \[5 \times 2 = 10\] and \[4 + 2 = 6\] which give you the coordinates: \[x = 2 ,~ y = 2\]
