Question

Eight times a number minus twenty-three is no more than the opposite of that number plus eighteen. Find that number.

Answer 1

8x - 23 = -x + 18 is how I'm interpreting your query.

"the opposite of the number" is slightly confusing, so I'm assuming you mean a negative. If not, please let me know.

We can solve for x using this equation.

8x - 23 = 18 - x

Add x to both sides

9x - 23 = 18

Add 23 to both sides

9x = 41

Divide both sides by 9

x = 4.56
