5y + 13 = 3
So we want to find the value of 'y' for when this expression is true.
So let's subtract 13 from both sides of the equation:
5y + 13 - 13 = 3 - 13
5y = - 10
Now we can divide both sides of the equation by 5 to find the value of 'y' :
(5y)/5 = ( - 10)/5
y = - 2
So this expression is true when y = - 2
