Answer 1

-1.0048 =x

Answer 2

y=2.44 approx

Answer 3

ok that helps. i also have the option to put infinitely many solutions of no solution.

Answer 4

or*

Answer 5

\[\Huge x = \frac{820}{19}, y = \frac{-850}{19}\]

Answer 6

i have to have is as an ordered pair

Answer 7

thanks you guys!!!! :)

Answer 8

0.3x - 0.2y=4 multiply by 0.5
--> 0.15 x-0.10y=2.0 (1)
0.5x+0.5y=-15/19 multiply by 0.2
-->0.10x+0.10y =- 0.15 (2)
==>(1)+(2)
0.25x=1.85
x=7.4
