There is a 7 in both 7x and 7 so you will take that out.
7 (x+1)
Then there is an x in both x2 and 2x so you take that out.
x (x+2)
If Lianne has some dimes and nickels with a total value of $4.60. The number of dimes she has is 4 more than 3 times the number of nickels then 0.15 Nickels does Lianne has.
<h3>What is Equation?</h3>
Two or more expressions with an Equal sign is called as Equation.
Given,
Lianne has some dimes and nickels with a total value of $4.60.
The number of dimes she has is 4 more than 3 times the number of nickels.
We need to find number of nickels
From the given information
N+D=4.60
D=3N+4
N+3N+4=4.60
4N=4.60-4
4N=0.6
Divide both sides by 4
N=0.15
Hence, 0.15 Nickels does Lianne has.
