simultaneous equation
First, find the LCD to get rid of the fractions
x/2+y/3=1
becomes
6(x/2+y/3=1)
multiply by the least common denominator then cross divide.
equaling
2x+2y=6
do the same for the second
x/4-y=11
- multiply for the LCD
- then cross divide, equalling:
x-4y=44
then line each equation up and see which variables will cancel each other
the Y will add up, only if they were positive and negative, so multiply by a 2.
cancel
solve for X,
- plug it in to the other equation.
- solve for Y
