and

y = -6

.

\newline

Write your answer as a decimal or whole number.

\newline

x - y + 5.8 =

_____

Identify Expression: Identify the expression to be evaluated. $\newline$ The expression given is $x - y + 5.8$ . We need to substitute $x = -3$ and $y = -6$ into this expression.
Substitute Values: Substitute the values of $x$ and $y$ into the expression. $\newline$ Substitute $x = -3$ and $y = -6$ into the expression to get: $(-3) - (-6) + 5.8$ .
Simplify Expression: Simplify the expression by performing the operations. $\newline$ Simplify the expression by adding and subtracting the numbers: $(-3) + 6 + 5.8$ .
Perform Addition: Perform the addition. $\newline$ Add the numbers together: $-3 + 6 = 3$ , and then add $5.8$ to get $3 + 5.8 = 8.8$ .
