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

If equation two is multiplied by -2 and then the equations are added, the result is .

result:

Step-by-step explanation:

First we multiply all the terms of the second equation with -2. So we have:

When we add them together the terms 2x and -2x will cancel out.

Hope it helped :)

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
