x= y=

2. anonymous

use a graphics calculator and graph them? And find its point of intersection.

3. anonymous

or you can do it via algebraic means. depends what is required

to graph it on your calc, we tend to get y on its own.

8. anonymous

$y _{1}=\frac{ 2.3+0.7x }{ 0.6 }$ $y _{2}=\frac{ -6.1-0.5x }{ 1.8 }$

9. anonymous

just graph these equation on your calculator and find its point on intersection

10. anonymous

you should get (-5,-2)

11. anonymous

You could also use a matrix and apply cramer's rule. and as @chris00 said you should get X = -5 , Y = -2

12. anonymous

depends if @Missiey is required to do it. I usually go the most quickest method if the question doesn't tell me to use a specific method

thanks chtis
