To solve you must make sure there are the same number of either x's or y's in both equations. We will call '2x-3y=24' equation 1, and '6x+2y=-5' equation 2. If you multiply equation 1 by 3 then you get '6...
First write down all the factor pairs of 12 (1,12) (-1,-12) (3,4) (-3,-4) (6,2) (-6,-2).
From these factors, find a pair that, when added together, is equal to -7.
In this case the correct p...
So to begin we need factors of 12.
12 and 1, 3 and 4.
Then we need to think of a way of adding or subtracting to give -1.
So we can have 4 and -3.
which gives (x+4)(x-3).
First off we can refer to the equations as equation 1 and equation 2. In order to solve the equations we must find a way to combine them that elimates one of the variables ( X or y) so that the other can ...
Here you have 2 equations and you need to find the value of x and of y. First we are going to find the value of x. We do this by eliminating the y factor by multiplying and adding the equations. If we mul...
