Question

How do you solve 2n-7=5n-10 and what's the answer?

Answer 1

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 

Answer 2

2n-7=5n-10
2n=5n-3
-3n = -3
n= 1
