Answer:
b
Step-by-step explanation:
on edge
3n + (4n - 2) = 15
is how this equation would be displayed.
Now let's solve for x.
We can distribute a 1 to each term in the parentheses (which doesn't do much) to allow us to combine like terms.
3n + 4n - 2 = 15
Combine like terms.
7n - 2 = 15
Add 2 to both sides.
7n = 17
Divide both sides by 7.
n = 17/7
Answer:
M=p-5n
Step-by-step explanation:
Here we are given that M+5n=p
We are asked to solve this equation for M. In order to do that we will follow these steps.
Subtracting 5n from both sides we get
M+5n-5n=p-5n
M=p-5n
Hence , now we have our M as dependent variable, whose value depends on the values of p and n. One or both of them can be independent variable/.
