X/4 - 12 = -18
x/4 -12 +12 = -18 + 12
x/4 = -6
x/4 times 4 = -6 times 4
x = -24
Check
-24 divided by 4 = -6 -12 = -18
It should be rm - n I THINK, i’m not sure
Answer:
Powers of ten
Step-by-step explanation:
They are the result of multiplying 1= times iteself however many times.
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
