Solve for m

Question

Give an exact answer.
4(1+0.5m) = 7m

Answer 1

To solve for m, let's start by distributing the 4 to both terms inside the parentheses:

4 + 2m = 7m

Next, let's isolate the term with m on one side of the equation. We can do this by subtracting 2m from both sides:

4 = 7m - 2m

This simplifies to:

4 = 5m

Finally, to solve for m, divide both sides of the equation by 5:

4/5 = m

So, the exact solution for m is m = 4/5.
