Four times a number is three times the difference between thirty five and the number?

Answer 1

Suppose the number is N

then 4N = 3*abs(35-N)

where abs(35-N) is the difference between 35 and N

If N > 35

then 4*N = 3*(N-35) = 3*N - 105

So N = -105

If N < 35

then 4*N = 3*(35-N) = 105 - 3*N

So 7*N = 105 ie N = 15

So N = -105 or 15
