Answer: x = 1, y = -2
Step-by-step explanation:
-9x+2y=-13
x= 13/9 + 2/9y
2x-9y=20
2(13/9+2/9y)-9y=20
<em>Substitute y with -2.</em>
<em />
x= 13/9+2/9(-2)
<em>After solving you'll see that 1 is a possible solution for x.</em>
<em />
Check your answer
-9x+2y=-13
-9x1+2(-2) = -13
2x-9y=20
2x1-9(-2) = 20
-13 = -13
20 = 20
Therefore, x=1 and y=-2

Do 12x-9 + 141 = 180 (add -9 and 4)
12x +132= 180 (Subtract 132 from 180)
12x =48 (Divide 48 by 12)
x=4
To a decimal you can round it down to .5 but if its a fraction no.
