Find the missing value. Hint: Use the number line to find the missing value. − 7 = −7=minus, 7, equals − ( − 2 ) −(−2)minus, left parenthesis, minus, 2, right parenthesis

Answer 1

Answer:

The missing value is -9

Step-by-step explanation:

Given

$-7 = _ -(-2)$

Required

Determine the missing value

Represent _ with a variable

$-7 = x -(-2)$

Open the bracket

$-7 = x -1*-2$

$-7 = x + 2$

Subtract 2 from both sides

$-7 - 2 = x + 2 - 2$

$-9 = x$

Reorder

$x = -9$

Hence, the missing value is -9
