I need help with 1 & 3.. thanks
AlekseyPX

Answer:

y/x = (a + b) / (m + n)

Step-by-step explanation:

-(xb − ym) = -yn + xa

Distribute:

-xb + ym = -yn + xa

Combine like terms:

ym + yn = xa + xb

Factor:

y (m + n) = x (a + b)

Rearrange:

y/x = (a + b) / (m + n)

Which expression is equivalent to 3-(-5)
Helen [10]

Here is the equation:

3-(-5)

When you're subtracting a negative number from a positive number, the sign will change. The - sign will become + and the negative number becomes positive.

3- \rightarrow 3+ \\ -5 \rightarrow 5

Here is your new equation:

3+5

All you need to do is add 3 and 5.

3+5=8

That means your answer is 8.
