Question

3 addef to 8 times a number is the same as 3 times the value of 2 times the number minus 1. What is the number?

Answer 1

The answer is -3.

Explanation:

3+8n=3(2n-1) would be the equation. To find the number, solve for n.

3+8n= 6n-3 First distribute the 3 to 2n and -1.

3+2n=-3 Subtract 6n from each side.

2n=-6 Subtract 3 from each side.

n=-3 Divide by 2 on each side.

n=-3 is your final answer :)
