Answer:
c = 3/2
Step-by-step explanation:
hello :
3(5-2x)=-4(cx+4)
-6x+15 = - 4 cx-16
-6x+4cx = -16-15 means 6x-4cx=-31
(6-4c ) x = 31
the equation have no solutions when : 6-4c = 0 (you have : 0x=31...false)
-4c=-6
c= -6/-4
c = 3/2
Answer:
Step-by-step explanation:
-9b + b = 2b - (b + 1)
Let's simplify by taking out the parenthesis.
-9b + b = 2b - b - 1
Now, we add like terms.
-8b = b - 1
Now, let's subtract b from both sides of the equal sign in order to isolate b.
-8b - b = b - 1 - b
Simplify!
-9b = -1
Divide both sides by -9.
-9b ÷ b = -1 ÷ -9
Simplify.
