Re-edited for clearing confusion.Danke Phantasm
Solve these simultaneous equations and find the values of x and y.
* Equation 1: 2x + y = 7
* Equation 2: 3x - y = 8
Add the two equations to eliminate the ys:
* 2x + y = 7
* 3x - y = 8
* ------------
* 5x = 15
* x = 3
OMFG .... I always hate math... blehhh
Oops Sorry i thought I'm still in f|a forum for games... OK got it so my browser didn't clean old forum cache I visited last time by accident and talking about math
O_O what the hell xD this is so simple solved in an other way xD
2x = 6 - 4y
-3 - 3y = 4x
take first equation and fint the x --> x = 3 - 2y
then substitute in the other equation --> - 3 - 3y = 12 - 8y
solve --> 5y = 15 --> y = 3
substitute in first equation --> 2x = -6 --> x = -3
and that's done
