Question

Solve for n.
d=4m + 7n
n

Answer 1

n = d - 4m ÷ 7

Explanation:

d = 4m + 7n

d - 4m = 7n

7n = d - 4m

n = d - 4m ÷ 7

Thus, n = d - 4m ÷ 7

Answer 2

n =
`(d-4m)/(7)`

Explanation:

Given

d = 4m + 7n ( subtract 4m from both sides )

d - 4m = 7n ( isolate n by dividing both sides by 7 )

`(d-4m)/(7)` = n
