Simplify the expression by combining like terms.

1/2d - 3/4d + 3f - 2f

-1 / 4 d - f

Step-by-step explanation:

Like terms imply that they have the same variables.

Therefore we grouped the "d"s together and the "f"s together.

1/2 d - 3/4 d + 3f - 2f

= (1/2 d - 3/4 d) + (3f - 2f)

= (1/2 - 3/4) d + (3 - 2) f

= - 1 / 4 d - f

-1 / 4 d - f

Step-by-step explanation:

1/2 d - 3/4 d + 3f - 2f

= (1/2 d - 3/4 d) + (3f - 2f)

= (1/2 - 3/4) d + (3 - 2) f

= - 1 / 4 d - f
