hope that helped
So n=number of nickles
d=number of dimes
n is 12 more than d so
n=12+d
but they have same amount of money so
n times 5=worth of nickles
d times 10=worth of dimes
5n=10d
divide both sides by 5
n=2d
subsitute
n=2d
n=12+d
2d=n=12+d
2d=12+d
subtract d from both sides
d=12
subsitute
n=12+d
n=12+12
n=24
24 nickles
12 dimes
Answer:
x...third number
4x...second number
x-9...first number
(x)+(4x)+(x-9)=141
x+4x+x-9=141
6x-9=141
Let's add 9 to both sides...
9+6x-9=141+9
6x=150
Let's divide both sides by 6...
(6x)/6=150/6
x=25
third number...25
second number...(4)(25)=100
first number...(25-9)=16
Let's check our work...
25+100+16=141
141=141
