To solve this equation in terms of m, you must isolate m to one side of the equation. To do so, see the following.
-2m%2B4=29-7m
First let us add 7m to both sides
-2m%2B7m%2B4=29-7m%2B7m=5m%2B4=29
Second let us subtract 4 from both sides
5m%2B4-4=29-4=5m=25
Third we divide each side by 5 to isolate the variable m
5m%2F5=25%2F5=m=5
Now that we have solved for m, let us check to see if that is the correct solution.
Substitute 5 for m in the original equation and solve following the order of operations.
-2%2A5%2B4=29-7%2A5
First do any multiplication
-2%2A5%2B4=29-7%2A5=-10%2B4=29-35
Then simplify any subtraction and/or addition
-10%2B4=29-35=-6=-6
Since both sides of the equation equal, which is what is called for, then m=-6 is the correct answer.
