Astudent is trying to solve the set of two equations given below:

equation a: x + z = 6
equation b: 2x + 4z = 1

which of the following is a possible step used in eliminating the z-term?

multiply equation b by 4.
multiply equation a by 2.
multiply equation a by −4.
multiply equation b by 2.

If you would like to eliminate the z-term, you can do this using the following steps:

x + z = 6       /*(-4)
2x + 4z = 1

-4x -4z = -24
2x + 4z = 1

-4x + 2x = -24 + 1
-2x = -23

x = 23/2

The correct result would be x + z = 6       /*(-4); multiply equation A by -4.

5/20 so 25%
