Answer: Therefore, the value of "a" that satisfies the equation is 6.
Step-by-step explanation: To solve the equation a - (7 - a) = 5, we can follow these steps:
Distribute the negative sign inside the parentheses:
a - 7 + a = 5
Combine like terms:
2a - 7 = 5
Add 7 to both sides of the equation to isolate the term with "a":
2a - 7 + 7 = 5 + 7
2a = 12
Divide both sides of the equation by 2 to solve for "a":
(2a)/2 = 12/2
