Question

Solve the equation for the indicated variable.

Equation: 2 - 4a - 6 + a = 0
A. a = -4/5
B. a = 8/5
C. a = -1/2
D. a = 1/2

Answer 1

To solve the equation 2 - 4a - 6 + a = 0, combine like terms and isolate the variable on one side of the equation. The solution is a = -1/2.

Step-by-step explanation:

To solve the equation, we need to combine like terms on the left side of the equation. So, we have 2 - 4a - 6 + a = 0. Simplifying this, we get -4a - 4 = 0. We can subtract 4 from both sides to isolate -4a, so -4a = 4.

Next, we divide both sides by -4 to solve for a, which gives us a = -4/4. Simplifying this fraction, we have a = -1.

Therefore, the correct answer is C. a = -1/2.
