Question 107700: Solve for y. x + 5y = 15
Answer by bucky(2189)   (Show Source):
You can put this solution on YOUR website! Given:
.
x + 5y = 15
.
to solve for y you want to get the y-term by itself on one side of the equation and get
everything else on the other side. So you want to get rid of the x on the left of the equation.
You can do this by subtracting x from the left side. But when you do that you must also subtract
x from the right side to keep the equation "balanced."
.
After the subtraction of x from both sides of the equation, the result is:
.
5y = -x + 15
.
Now you can solve for x by dividing both sides of this equation (all terms) by 5 (because 5 is
the multiplier of y). After this division of all terms by 5, the equation becomes:
.
y = -(x/5) + 3 which could also be written as y = -(1/5)x + 3
.
That's the answer. Hope that this helps you to understand the problem better.
