I need help understanding how to slove two step equations. Example -10 - k=-36
The idea is to get the constants on one side, variables on the other. Here,
add 10 to each side.
Then, multiply each side by -1
To solve a two-step equation like -10 - k = -36, follow these steps:
Step 1: Isolate the variable term
Start by isolating the variable term, which in this case is the variable "k". In order to do this, you need to move any constant terms to the other side of the equation.
-10 - k = -36
To move the constant term -10, you need to add 10 to both sides of the equation:
(-10 + 10) - k = (-36 + 10)
Simplifying:
0 - k = -26
This simplifies further to:
-k = -26.
Step 2: Solve for the variable
Now that we have isolated the variable term, we can solve for "k" by getting it by itself. In order to do this, we need to get rid of the negative sign that is attached to the variable "k".
Since -k is the same as saying -1 * k, we can get rid of the negative sign by multiplying both sides of the equation by -1.
(-1) * (-k) = (-1) * (-26)
Simplifying:
k = 26
Therefore, the solution to the equation -10 - k = -36 is k = 26.
