Answer :
2n - 7 = 5n - 10
Subtract 2n from both sides to get the 2 n's on the right
-7 = 3n - 10
Add 10 to both sides to get the two numbers on the left
3 = 3n
Divide both sides by 3 to solve for n
n = 1
Subtract 2n from both sides to get the 2 n's on the right
-7 = 3n - 10
Add 10 to both sides to get the two numbers on the left
3 = 3n
Divide both sides by 3 to solve for n
n = 1
