Answer

The answer is (m = 9)

Explanation:

Rearrange terms = Step 1

0.4(20-10m) = 2.5 - 2m-12.5

0.4(-10m+20) = 2.5 - 2m - 12.5

Step 2 = Combine multiplied terms into a single fraction

Step 3 = Distribute

Step 4 = Subtract the numbers

Step 5 = Rearrange terms

Step 6 = Add 2m to both sides

Step 7 = Simplify

Step 8 = Multiply all terms by the same value to eliminate fraction denominators

Step 9 = Cancel multiplied terms that are in the denominator

Step 10 = Multiply the numbers

Step 11 =Subtract 40 from both sides

Step 12 = Simplify

Step 13= Divide both sides by the same factor

Last but not least is Simplify

Hope it helped:)
