Question

How many solutions does the equation have?

y+7=y–3

many solutions

no solutions

1 solution

Answer 1

This equation has no solutions

Answer 2

In order to find out if the following equation has solutions or not, we have to solve it:

y+7=y-3

y-y=-3-7

0=-10 This has no logic, because 0 is not equivalent to -10

In fact:

`0\\eq-10`

Then, this equation does not have a logic solution
