47. Solve for the variable in the equation: 3.4 = -13.6 + (-3.4c) + 1.7c
c=-10
That is what I got.
yes, correct. I am reminded of the lecture I gave you yesterday in response to a question that said all equations used x as a variable. Duh.
To solve for the variable "c" in the given equation: 3.4 = -13.6 + (-3.4c) + 1.7c, we can follow these steps:
1. Combine like terms: By adding -3.4c and 1.7c, we get -1.7c.
Thus, the equation becomes: 3.4 = -13.6 - 1.7c.
2. Isolate the variable: To isolate the variable "c," we need to move the constant term (-13.6) to the other side of the equation.
- To do this, we add 13.6 to both sides of the equation:
3.4 + 13.6 = -1.7c
Simplifying the left side gives us: 17 = -1.7c
3. Solve for "c": To solve for "c," divide both sides of the equation by -1.7.
(17) / (-1.7) = (-1.7c) / (-1.7)
Doing the calculations, we get: c = -10
So, you are correct. The value of the variable "c" in the equation 3.4 = -13.6 + (-3.4c) + 1.7c is indeed -10.
