help will medal

Answer 1

x=
y=

Answer 2

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

Answer 3

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

Answer 6

what was your answer?

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

you should get (-5,-2)

Answer 11

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

Answer 12

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
