Step-by-step explanation:
9x - 2x = 8 + 5
7x = 13
x =13÷7
x = 1.8571
approximately = 1.86
I think this is it
Listening music and watching some movies
Rearrange x/4-(-5)=0
Simplify x/4
-5 = -5/1 = -5*4/4
x- (-5*4)/4 = x+20/4
x+ 20/4 = 0
x+20/4 * 4 = 0*4
The equation now takes the shape: x+20=0
subtract 20 from both sides of the equation: x=-20
Answer: x=-20
