Question

What is two less than 2 times a number is the same as the number plus 64 what is the number.

Answer 1

Answer: n=66

Explanation:

2n -2 = n + 64 subtract 1n on both sides

- n - n The n’s cancel out

————————

1n - 2 = 64 Add 2 on both sides

+2 +2 The 2’s cancel out

——————-

1n = 66 Divide 1 on both sides

—- ——

1 1 The 1’s cancel out

n= 66

Check it :

2(66) - 2 = 66 + 64

132 - 2 = 130

130 = 130
