2y-4=3y-5
-4=y-5
1=y
Answer: y=1
<span>Subtraction exhibit a property of closure over the set of real numbers because if you subtract two numbers from the real numbers set, the result will still be a real number.
Example:
Let RS be a set of real numbers.
RS = {1, 2, 3}
Suppose I get 3 and subtract 1, 3 - 1, the result is 2 which is a real number. We can try a non-commutative 1 - 3 and yet it will still give us a real number which is -2.
</span><span>Subtraction is non-commutative because if we interchange numbers in subtraction, the result will either be positive or negative.
Example:
3 - 1 = 2. The answer is 2; but we can not say this is true for 1 - 3 because it will yield -2.

Answer:
- No solution for x, when k = 1
- x = 68/(k - 1), when k≠ 1
Step-by-step explanation:
<u>Given the equation</u>
- kx – 17 = 51 + x, where k = 1,
<u>Solve for x:</u>
- 1*x - 17 = 51 + x
- x - 17 = x + 51
- x - x = 51 + 17
- 0 = 68,
Incorrect equation, no solution for x when k=1
<u>Solving for x when k ≠ 1</u>
- kx - 17 = 51 + x
- kx - x = 51 + 17
- x(k - 1) = 68
- x = 68/(k - 1)
