Answer:
Step-by-step explanation:
That question is asking you find the value of m. What you do is, remove the brackets by multiplying + and - out. You will get
4m - 1=2, moving minus 1 to the right hand side, so that you have the 4m on its own side. Minus 1 become positive, if a number cross the equal sign the sign changes.
You will now have
4m = 2 +1
4m = 3
Diving through with 4 gives
m = 3/4
And that's the answer
