Reduce the fraction 4/10, to its minimum expression, extracting and canceling 2.
Combine
and -2x to get
.
Subtract 8/5 from both sides.
Since 4/5 and 5/8 have the same denominator, join their numerators to subtract them.
Subtract 8 from 4 to get -4.
Multiply both sides by
, the reciprocal of
.
Multiply -4/5 by -5/8 (to do this, multiply the numerator by the numerator and the denominator by the denominator).

D) 180 because there are 180 possible combinations for the marbles to be picked out
To find y, divide the first equation by 2.
y = 4
To find x, use that value for y in the second equation. Add 4, then divide by 2.
15·4 = 2x -4
60 +4 = 2x
64/2 = x = 32
The solution is (x, y) = (32, 4).
