4 n − 3 = − 2 n + 15 4 n + 2 n = 15 + 3 6 n = 18 x = 6 18 = 3
isolate n
4n-3=-2n+15 4n+2n-3=-2n+2n+15 6n-3=15 6n-3+3=15+3 6n=18 6n/6=18/6 n=3
To solve the equation 4 n − 3 = − 2 n + 15 , first isolate the variable by moving the terms involving n to one side. After simplifying, you find that n = 3 .
