Question

x-5=0 find the equation​

Answer 1

Answer:

x=5 is your answer

Answer 2

Answer:

First, you could subtract 5 from both sides. x+5−5=0−5 . 5 - 5 is 0, and 0 - 5 is -5, so we’re left with x+0=−5 . x + 0 is just x, so we’re left with x=−5 .

The other algebraic answer is less efficient and less obvious, but I’ll still go through it. Instead of subtracting 5 from both sides, we could subtract x from both sides. x+5−x=0−x . The positive and negative x’s on the left side cancel each other out (because anything minus itself is 0, or algebraically: x−x=0 ). So we then have 5=0−x . Zero minus something is the opposite of that thing, so 0 - x is -x, and we’re left with 5=−x . -x can be thought of as -1 * x, and -1 * -1 is positive 1, so if we multiply both sides of the equation by -1, we’re left with −5=x , which can be rewritten as x=−5 if you prefer. Notice this is the same answer as we got solving the other way.
