Answer:
Simplifying
-38 = -0.4k
Solving
-38 = -0.4k
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '0.4k' to each side of the equation.
-38 + 0.4k = -0.4k + 0.4k
Combine like terms: -0.4k + 0.4k = 0.0
-38 + 0.4k = 0.0
Add '38' to each side of the equation.
-38 + 38 + 0.4k = 0.0 + 38
Combine like terms: -38 + 38 = 0
0 + 0.4k = 0.0 + 38
0.4k = 0.0 + 38
Combine like terms: 0.0 + 38 = 38
0.4k = 38
Divide each side by '0.4'.
k = 95
Simplifying
k = 95
