-13=5(1+4m)-2m
First you need to simplify the equation by getting rid of parentheses.
-13 = 5 + 20m - 2m
To solve the equation -13=5(1+4m)-2m, you will need to simplify the expression on the right side of the equation and then isolate the variable, m, on one side.
Let's break it down step by step:
1. Distribute the 5 to both terms inside the parentheses:
-13 = 5 + 20m - 2m
2. Combine like terms on the right side:
-13 = 5 + 18m
3. Move the constant term (5) to the left side by subtracting it from both sides of the equation:
-13 - 5 = 18m
-18 = 18m
4. Divide both sides of the equation by 18 to solve for m:
-18/18 = m
-1 = m
So, the solution to the equation is m = -1.
