9n + 18 = 54
Deduct 18 from each side: 9n = 36
Divide both sides by 9: n = 4
Easy, intit?
negative
That equation has no solution. There is no possible number that's equal to 18 more than itself.
The expression "p plus 18" can be written mathematically as ( p + 18 ). If you want to solve for ( p ), you would need to know what ( p + 18 ) equals. For example, if ( p + 18 = 30 ), you would subtract 18 from both sides to find that ( p = 12 ).

3(x + 2) = x - 18 3x + 6 = x - 18 3x - x = -18 - 6 2x = -24 x = -12

8-8x=8x+18 Through simple algebra, this can be manipulated to solve for x: 8=16x+18 -10=16x -5/8=x
24 + 18 + 20 + 22 = 84
-11=18+s/5
