See a solution process below:

Explanation:

First, divide each side of the equation by color(red)(5) to eliminate the parenthesis while keeping the equation balanced:

(5(m + 3.2))/color(red)(5) = 15/color(red)(5)

(color(red)(cancel(color(black)(5)))(m + 3.2))/cancel(color(red)(5)) = 3

m + 3.2 = 3

Now, subtract color(red)(3.2) from each side of the equation to solve for m while keeping the equation balanced:

m + 3.2 - color(red)(3.2) = 3 - color(red)(3.2)

m + 0 = -0.2

m = -0.2

the answer is m=-1/5

Explanation:

distribute 5 to the inside equation
5m+16=15
subtract -16 to both sides
5m=-1
divide by 5 to both sides
m=-1/5
