How do you solve 3/2y-y=4+.5y?

See a solution process below:

Explanation:

First, convert 3/2 to:

3/2 = (2 + 1)/2 = 2/2 + 1/2 = 1 + 1/2 = 1 + 0.5 = 1.5

We can rewrite the problem as:

1.5y - y = 4 + 0.5y

Next, we can combine like terms on the left side of the equation:

1.5y - 1y = 4 + 0.5y

(1.5 - 1)y = 4 + 0.5y

0.5y = 4 + 0.5y

Now, we can subtract color(red)(0.5y) from each side of the equation to show there is no solution:

0.5y - color(red)(0.5y) = 4 + 0.5y - color(red)(0.5y)

0 = 4 + 0

0 != 4

Because 0 is obviously not equal to 4 there is no solution for this problem

Or, the solution is the null or empty set: {O/}

No solutions

Explanation:

3/2 is the same thing as 1.5. With this in mind, we can rewrite our equation as

1.5y-y=4+0.5y

We have two y terms on the left, so we can simplify them to get

0.5y=4+0.5y

Something already looks suspicious...let's subtract 0.5y from both sides to get

0=4

This is obviously not true, which means no value of y satisfies this equation.

Hope this helps!
