Hello!
<u><em>Explanation: Addition property of equality is adding the same number to both sides of an equation does not change the equation.</em></u>
<u><em>a+c=b+c</em></u>
<u><em>First, add by 23 both sides of an equation.</em></u>
<u><em>y-23+23=-5+23</em></u>
<u><em>And then, simplify.</em></u>
<u><em>23-5=18</em></u>
<u><em>It changes negative to positive sign.*</em></u>
<u><em>Final answer is y=18</em></u>
<u><em>Hope this helps!</em></u>
<u><em>Thanks!</em></u>
<u><em>Have a great day!</em></u>
