Given <span>x-3/4=x/10 find the LCD. It is 20, as both 4 and 10 divide evenly into 20.
Then you have 20x - 15 = 2x, or 18x = 15, or x = 15/18, or x =5/6 (answer).</span>
Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for y: ...
Step 2: Substitute that equation into the other equation, and solve for x. ...
Step 3: Substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

Answer: 
Step-by-step explanation:
Given : Total rolls of film in the box = 10
Defective rolls =3
Probability of selecting first defective roll = 

Now , total rolls left = 9
Total defective rolls left = 2
Probability of selecting second defective roll = 

Now , the probability of selecting a defective roll followed by another defective roll = 
Hence, the probability of selecting a defective roll followed by another defective roll is
.
