Question

−(5,1y+18x)−(−16y−2,3x)=

Answer 1

-5,1y-18x+16y+2,3x
10,9y-15.7x

Answer 2

To simplify the expression −(5,1y+18x)−(−16y−2,3x), let's distribute the negative sign through the first parentheses and the negative sign in front of the second parentheses.

-(5.1y + 18x) - (-16y - 2.3x)

First, distribute the negative sign inside the first parentheses:

-5.1y - 18x - (-16y - 2.3x)

Now, simplify the expression inside the second parentheses by changing the signs:

-5.1y - 18x + 16y + 2.3x

Next, combine like terms:

(-5.1y + 16y) + (-18x + 2.3x)

Simplifying further:

10.9y - 15.7x

Therefore, the simplified expression is 10.9y - 15.7x.
