Answer:
Use a formulae calculator on Google
D=M/V. You just multiply both sides by D to get DV=M, then divide V by both sides.
Ann = 3 CD's
Ann = 2x-3
5 = 2x-3
x= CD's bob has
5 = 2x-3 is the equation
to solve
add 3 to each side
8 = 2x
divide by 2
x =4
bob has 4 CD's, ann has 5
The answer is x=2
explanation:
2+3=5
8 times 2 is 16, minus 11=5
