Question

How many solutions exist for the given equation?

1/2(x + 12) = 4x – 1
1.zero
2.one
3. two
4. infinitely many

Answer 1

One solution

Explanation:

To solve this problem, isolate x.

1/2(x + 12) = 4x - 1

Dividing 1/2 from both sides, we get x + 12 = 8x - 2

Subtracting 12 from both sides, we get x = 8x - 14

Subtracting 8x from both sides, we get -7x = -14

Dividing -7 from both sides, we get x = 2

Since this problem is able to be solved with only one answer, there is one solution: x = 2.

Answer 2

one

Step-by-step explanation: you cant simplify the equation so that both sides can be divided to get the same equation, if you graph it theres not a parabola so the only thing left is one.
