3X plus 5Y is equal to 40 X is equal to 2 what is the value of Y

Answer: The value of yy is 345\frac{34}{5}.

Step-by-step solution

Step 1: Substitute the value of xx

We are given the equation 3x+5y=403x + 5y = 40 and the value of x=2x = 2. To find the value of yy, we substitute x=2x = 2 into the equation.

Step 2: Simplify the equation

After substituting x=2x = 2, we multiply 33 by 22 to simplify the equation. This gives us 6+6 + 5y=405y = 40.

Step 3: Isolate the term with yy

To isolate the term with yy, we subtract 66 from both sides of the equation. This moves the constant term to the right side.

Step 4: Calculate the value of 5y5y

Subtracting 66 from 4040 gives us 3434. So, the equation becomes 5y=345y = 34.

Step 5: Solve for yy

To find the value of yy, we divide both sides of the equation by 55. This isolates yy and gives us its final value.
