N=3.
It depends on the value of n.
15 + n = 24 (subtract 15 from both sides) n = 9
N+18=30. Subtract 18 both sides N=12

N=3.
It depends on the value of n.
if you put in what the problem equals then it can be answered
15 + n = 24 (subtract 15 from both sides) n = 9
N+18=30. Subtract 18 both sides N=12
-24
for n=4: (4 x 5) + 4 = 24
-24
n = 5 so both sides are equal
1. n + 3*5 = 30 2. n + 15 = 30 3. n + 15 = 30 - 15 -15 n = 15
3n=24 n=8
