Two less than 2 times a number is the same as the number plus 64. What is the number?
2 answers:
Let n be the number unknown
2(n)-2=n+64
Use distribute property to remove parenthesis
2n-2=n+64
Move all n term to left side
2n-n-2=64
Combine like terms with n
N-2=64
Now add integer to right side by doing opposite sign
N = 64+2
Solve for n
N=66
Your number is 66
To check you substitute
2(66)-2=66+64
130. =130
What is 3 times the number?
3*66 = 198
