How many solutions are there to the equation below?
220=2x-12x
a.1
b. Infinitely many
c.2
To determine the number of solutions to the given equation, we need to solve it and see if there is a unique solution, infinitely many solutions, or no solution.
The given equation is:
220 = 2x - 12x
To solve for x, we can start by combining like terms on the right-hand side of the equation:
220 = -10x
Next, we isolate x by dividing both sides of the equation by -10:
220 / -10 = -10x / -10
Simplifying further gives us:
-22 = x
So, we have found a solution: x = -22.
Since we have found a unique value for x, there is only one solution to the equation. Therefore, the answer is:
a. 1
x = -22
You can solve that :)
