a student is trying to solve the system of two equations given below:

equation p: x + y = 8
equation q: 2x + 5y = 24

which of the following steps can be used to eliminate the x term?
2(x + y = 8)
−2(x + y = 8)
−1(2x + 5y = 24)
−2(2x + 5y = 24)

If you use the first answer, the equation becomes 2x + 2y = 16.  You could subtract this from equation Q to eliminate x.

The second answer makes equation P -2x - 2y = -16.  You could add this to equation Q to eliminate x.  You can use both of these methods to eliminate the x term, but if you can only choose one, you should choose the second option.

1.3 and 1 1/3 are both closest to 1. hope this ; )
