Question

-5×-16=9×+×-1 how do I slovenly this problem

Answer 1

-5x-16=9x+x-1
Combine the like terms (terms with no or the same variable)
-5x-16=10x-1
now you can group like terms so they're all on one side:
-5x -16 = 10x -1
-10x +16 -10x +16
-15x = 15
Now divide both sides by 15
-x=1
x=-1

Hope this helps :)

Answer 2

-5x-16=9x+x-1 First, you want to combine like terms on each side.
-5x-16=10x-1 Then, you want to cancel out alike terms.
+5x +5x
-16=15x-1 Continue...
+1 +1
-15=15x Divide each side by the number in front of x to get x alone.
