Question

Describe in your own words how you can tell whether an equation has an infinite number of solutions or no solution at all.

(I will not plagiarize your answer, I promise.)

Answer 1

if x=x or x≠x

Explanation:

2x + 3 = x + x + 3 has infinite solutions, if we solve it, 2x+3=2x+3. this is true meaning we can substitute x for ANY number, and it will still be the same, for example if x=5, then 2(5)+3=5+5+3 13=13 so its infinite solutions. Basically, the sades have to equal each other. No solution would be like 2+n=n+1+7 so then we would solve it and it would be 2=8, we know this is not true so there is no solution. They are not equal to eachother
