The solution to this equation is in the picture i’ve put below!
.25x+.10y=$10
.25 because that is the value of the quarter, times x the number or quarters you have and .10 because that is the value of the dime times y, the number of dimes you have.
20/5
4x/x adding 10 to each
4x+10/x+10 =2
Multiple x+10 to each side
4x+10=2x+20
Then subtract and get
2x=10
Divide
X=5
Now plug it back in
20/5
4^x+3 (the x + 3 is included in the power). That's just another way that you could write that.
