Question

2(x)-(3-y) если х=-7, y= -12

Answer 1

2•(-7)-(3+12)=-14-15=-29

Answer 2

To evaluate the expression 2(x) - (3-y) with x = -7 and y = -12, we substitute the given values into the expression and perform the calculations:

2(-7) - (3-(-12))

First, let's simplify the expression inside the parentheses:

2(-7) - (3 + 12)

Next, we evaluate the addition inside the parentheses:

2(-7) - 15

Now, we multiply 2 by -7:

-14 - 15

Finally, we perform the subtraction:

-29

Therefore, when x = -7 and y = -12, the value of 2(x) - (3-y) is -29.
