Let the number be x. By the given statement we can make an equation. 1/2 * x = 18 + 5*x Which gives x = -4. So the number is -4.
"More" in a word problem means addition is involved. "Half" indicates division by 2 (or multiplication by 1/2). "A number" means a variable, so we can us x. Finally, "is" mean equals. So, 15 more than half a number is 19 would be represented as follows: 15 + x/2 = 19 Solving this, we get: 15 + x/2 = 19 x/2 = 4 x = 8
the majority is the number more than half the total number of a given group.

The solution set is the answers that make an equation true. So I would call it the solution.

I'll represent the unknown value of the number with the variable 'n'.9 + (n/2) = 24This is the equation, now to solve it, solve for n.18/2 + n/2 = 24(18+n)/2 = 2418 + n = 48n = 30
The equation is: 18N+2 = 19N
If the number is N, then 3 more is N+3, set equal to 7: N+3=7
Then the whole number is negative.
I must change your description to read " ... 3 times as much as ... ".Then the equation is 0.33 N = 3 x (0.17 N) . The equation has no solution. That means that no numbercan make the equation a true statement.
Have you even gotten as far as writing the equation that comes from the words ?Here's the equation:(x/2) = (x/3) + 3We're quite sure you can handle it from there.
