Suppose your given the formula n=3m-2l if you know that l= m+2 how could you rewrite that formula

n=m+4

given formula,

n=3m-2l

and,

l=m+2

here in this question We have to substitute the values of "l" in the formulae

we get,

n=3m-2(m+2)

n=3m-2m+4

n=m+4

so if we complete the process correctly we get n=m+4
