Help please
Choose the equivalent system of linear equations that will produce the same solution as the one given below.

4x - 2y = 6
2x + y = 5
_______________________________________________
-4x - 2y = 10
-4y = 4

-4x - 5y = -1
-7y = 5

3x + 2y = 6
7x = 12

4x + 2y = 10
8x = 16

@AllTehMaffs @campbell_st @BulletWithButterflyWings @charlotte123 @phi @Preetha @hba please help.

campbell_st · Answer

so my suggest is find the solution to the 1st pair, then substitute into each possible pair

campbell_st · Answer

because what you are being asked to do is find a pair of equations that have the same point of intersection as the 1st pair listed in the question. 

If you know the point, you can just substitute x and y into each equation. 

hope this helps
