Question

question 20 of 40
solve $2 - x = -7$.
a. $x = -9$
b. $x = -5$
c. $x = 5$
d. $x = 9$

Explanation:

Step1: Isolate the variable term

Start with the equation \(2 - x = -7\). Subtract 2 from both sides to get \(-x=-7 - 2\).
\(-x=-9\)

Step2: Solve for x

Multiply both sides by -1 to solve for \(x\). So \(x = 9\).

Answer:

D. \(x = 9\)
