-13=5(1+4m)-2m
-13=5(1+4m)-2m
-13 = 5 + 20m - 2m
-18 = 18m
-1 = m
To solve the equation -13 = 5(1 + 4m) - 2m, we will need to simplify and isolate the variable "m."
Step 1: Distribute the multiplication
-13 = 5 + 20m - 2m
Step 2: Combine like terms
-13 = 5 + 18m
Step 3: Move the constant term to the other side of the equation
-13 - 5 = 18m
Step 4: Simplify
-18 = 18m
Step 5: Divide both sides of the equation by 18 to isolate "m"
-18/18 = m
Step 6: Compute the result
m = -1
Therefore, the solution to the equation -13 = 5(1 + 4m) - 2m is m = -1.
