Answer:
A standard deck contains 52 cards with 4 suits and hence 4 tens. The probability of being dealt 3 tens is thus 4/52 x 3/51 x 2/50. The denominator decreases as one card is removed from the deck each time. If the removed card is replaced, there would be no need for the decrease in the denominator.

P.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Helvetica Neue'; color: #454545}
p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Helvetica Neue'; color: #454545; min-height: 14.0px}
Simplifying
3x + 7y = 28
Solving
3x + 7y = 28
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7y' to each side of the equation.
3x + 7y + -7y = 28 + -7y
Combine like terms: 7y + -7y = 0
3x + 0 = 28 + -7y
3x = 28 + -7y
Divide each side by '3'.
x = 9.333333333 + -2.333333333y
Simplifying
x = 9.333333333 + -2.333333333y
