Simplify the expression. -2.5f + 0.4f - 14 - 3?

-2.1f-17

Step-by-step explanation:

1. Combine like terms

Like terms are those that either have the same variable, degree, or no variable at all.

Here, -2.5f and 0.4f and -14 and -3 are like terms. -2.5f and 0.4f are like terms because they both have f beside them. The reason -14 and -3 are like terms is because they both stand alone with no variables.

Combining like terms means to either add or subtract them from each other depending on their signs.

Just think of them as two separate problems for now.

-2.5f + 0.4f = ?

add these two together to get -2.1f

-14-3

Subtract these to get -17.

2. Put the expression back together: -2.1f-17

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
