My bad, you are correct!
15-20 is -5, 20-15 is 5
-3(x-5)=20
-3(x) -3(-5)=15
-3x+15=20
15-20=-5
-3x=-5
-3x/-5=0.6
x=0.6
Wouldnt you stop at
8x=1x
8x-1x=7x
7x=0 OH I GET IT cause you HAVE to have the x By its self!
Why did you bring in the 0 out of no where?
How did you get the zero from
4x=1/2
I think you use GEMDAS
So
20/-25= -0.8
-0.8+5=4.2
4.2-2 = 2.2
3.14
15
