the following proof shows an equivalent system of equations created from another system of equations. fill in the missing reason in the proof.
statements reasons
2x + 2y = 14
-x + y = 5
given
2x + 2y = 14
-2x + 2y = 10
a. multiplication property of equality
b. addition property of equality
c. division property of equality
d. subtraction property of equality

Step-by-step explanation:

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
