Two different things u can do
Substitution:
X-9y=12
+9y +9y
X=9y+12
-3(9y+12)+9y=36
-27y-36+9y=36
+36 +36
-18y = 72
/-18 /-18
Y = -4
Or whatever this other I’ve is called
-3x-9y=36
-1(X-9y)=(12)-1
-3x-9y=36
-x+9y=-12
-4x=24
X= -6
If you would like to know the simplified expression for 2 * (x - 5), you can find this using the following steps:
2 * (x - 5) = 2 * x - 2 * 5 = 2 * x - 10
The correct result would be <span>2 * x - 10.</span>
Answer:
The answer is x = -6
