To combine like terms and single out one term to take it easier to solve, the 6x was moved to the other side to combine like terms.
Subtracting 6x from 10x which is 4x
If the given quantities are 10 quarters 17 dimes 40 nickels 15 pennies then the total money would be 6.35 dollars.
<h3>What is the fundamental principle of multiplication?</h3>
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Quarters are worth .25 of a dollar
10 x .25 = 2.5
Dimes are worth .10 of a dollar
17 x .10 = 1.7
Nickels are worth .05 of a dollar
40 x .05 = 2
Pennies are worth .01 of a dollar
15 x .01 = 0.15
Add this together
2.5 + 1.7 + 2 + 0.15
= 6.35
