Answer:

<h2>-3.5</h2>

Step-by-step explanation:

The given expression is

-21.8-(-18.3)

To find a equivalent expression to the given one, we have to first eliminate the parenthesis by multiplying the negative sign with the number inside

-21.8+18.3

Now we eliminated the parenthesis, we have to subtract these numbers, because they have different signs, the result will be negative because they major absolute value is in the negative number

-21.8+18.3=-3.5

Therefore, the given expression is equal to -3.5

Answer:

X = 1

Y = 5

Step-by-step explanation:

we have to figure out what x and y = that make both answers correct

3 x 1 = 3

3 + 5 = 8

That means that the first equation is right with X = 1 and Y = 5

Let's see the second equation

5 x 1 = 5

5 + 5 = 10

That means both equations are right so the answer would be

X = 1 and

Y = 5
