solve the equaiton 3x + 5y = 15 for y
To solve the equation 3x + 5y = 15 for y, you need to isolate y on one side of the equation.
Starting with the given equation:
3x + 5y = 15
To isolate y, subtract 3x from both sides:
5y = 15 - 3x
Now, divide both sides of the equation by 5 to solve for y:
y = (15 - 3x)/5
Therefore, the expression for y is (15 - 3x)/5.
To solve the equation 3x + 5y = 15 for y, we can follow these steps:
Step 1: Start with the equation: 3x + 5y = 15
Step 2: Move the term containing 3x to the other side of the equation by subtracting 3x from both sides:
3x + 5y - 3x = 15 - 3x
Simplifying this, we get:
5y = 15 - 3x
Step 3: Divide both sides of the equation by 5 to isolate y:
(5y)/5 = (15 - 3x)/5
Simplifying further, we have:
y = (15 - 3x)/5
So, the equation 3x + 5y = 15, when solved for y, is:
y = (15 - 3x)/5
To solve the equation 3x + 5y = 15 for y, we need to isolate the variable y on one side of the equation.
Step 1: Begin by subtracting 3x from both sides of the equation:
3x + 5y - 3x = 15 - 3x
This simplifies to:
5y = 15 - 3x
Step 2: Now, divide both sides of the equation by 5 to isolate y:
(5y)/5 = (15 - 3x)/5
This simplifies to:
y = (15 - 3x)/5
Therefore, the solution for y is (15 - 3x)/5.
