In the equation, the value of y will be different as a result of the signs that are used.
<h3>How to solve the equation</h3>
In the first equation, 5y + 10 = 25. To find the value of y goes thus:
5y + 10 = 25
5y = 25 - 10
5y = 15
y = 15/5 = 3
Also, 5y - 10 = 25
5y = 25 + 10
5y = 35
y = 35/5 = 7
The values of y are 3 and 7.
