Simplify by combining like terms.2/8x+3/10y−5/8x+4/10y

Answer 1

To simplify the expression 2/8x + 3/10y - 5/8x + 4/10y, we can combine the like terms.

First, let's combine the x terms: 2/8x - 5/8x.
Since the denominators are the same, we can combine the numerators: (2/8 - 5/8)x = -3/8x.

Next, let's combine the y terms: 3/10y + 4/10y.
Since the denominators are the same, we can combine the numerators: (3/10 + 4/10)y = 7/10y.

Therefore, the simplified expression is -3/8x + 7/10y.
