12d-3d= 9d + 2 = 5
Subtract 2 from both sides you get
9d= 3
Divide by 9 by both sides
D= 0.33
Answer:
-3/20
Step-by-step explanation:
12 * x + 3 = -8x
Make sure to use PEMDAS.
12x + 3 = -8x
Add 8x to both sides of the equation.
20x + 3 = 0
Subtract 3 to get 20x alone.
20x = -3
Divide both sides by 20.
x = 
Answer:
yes
Step-by-step explanation:
if you distribute the 9 into the parenthesis you get 9y + 45. Therefore, both equations are equivalent seeing that they both equal to 9y + 45.
Answer:
Step-by-step explanation:
Given the expression 3x + 5/16 = 3/4 - 1/8x - 1/2
First we need to use the multiplication prope-rty before combining the like terms. The importance of this is to covent all fraction's to whole numbers.
Multiply through by 16
48x+5= 12-2x-8
Next is to collect the like terms
48x+2x = -8+12-5
50x = -1
Divide both sides by 50
50x/50 = -1/50
x = -1/50
The value used to multiply both sides is 16 and the value of x is -1/50
Answer: n=3
Step-by-step explanation:
Divide by - 2
(N+3) = 6
Subtract 3
N= 3
