Question

can someone show me the steps to this problem 17 + 2n = 21 - 2n

Answer 1

first get the constants and the varibles on different sides by subtracting 17 from bothe sides and adding 2n to both sides...4n=4..then divide each side by 4...x=1

Answer 2

17 + 2n = 21 - 2n

2n + 2n = 21 - 17

4n = 4

n = 4/4

n = 1

Answer 3

so is this a solution
