Answer 2

To solve the equation (5/12)y - (4/15)y = 2 + 1/4, you need to combine like terms on the left side and then isolate y. Here are the steps:

Step 1: Combine like terms on the left side of the equation:

(5/12)y - (4/15)y = 2 + 1/4

To combine fractions, you need a common denominator, which in this case is 60. So, let's rewrite the fractions with a common denominator:

[(5/12) * 5/5]y - [(4/15) * 4/4]y = 2 + 1/4

Now, we have:

(25/60)y - (16/60)y = 2 + 1/4

Step 2: Subtract the fractions on the left side:

(25/60)y - (16/60)y = (25/60 - 16/60)y

(9/60)y = (25/60 - 16/60)y

(9/60)y = (9/60)y

Step 3: Divide both sides by (9/60) to isolate y:

y = (9/60)y / (9/60)

Now, you can simplify the right side by multiplying by the reciprocal of (9/60), which is (60/9):

y = [(9/60)y] * (60/9)

y = (9/60) * (60/9)y

y = (1/6)y

So, the solution to the equation is:

y = (1/6)y

Now, this equation is true for any value of y because you essentially have y = (1/6)y, which means y is equal to itself. This means there are infinitely many solutions for y, and any real number can be a solution.
