3x-7=5x=19
3x-7-5x=5x+19-5x
-2x-7=19
-2x-7+7=19+7
-2x=26
-2x/-2=26/-2
x=-13
:) Did you get that?

Answer:
The other solution is 12.
Step-by-step explanation:
Break the solution into groups: (x^2+2x)+(-12x-24)
Factor out the x^2 from the first group to get x(x+2)
Factor out the -12 out of the second group to get -12(x-12)
Here we get (x-12)(x+2)
You can see solutions are -2 and 12.
Answer:
b=-1
Step-by-step explanation:
given.3b+(-5)=(2b)³(-3)2+6=?
3b-5=8b-6+6
3b-5=8b
-5=8b-3b
-5=5b
-5/5=5b/5
b=-1
-3-5=-8-6+6=?
-8=-8=-8
