    you may start by distributing. \( \color{Black}{\Rightarrow -11-7m = -4m + 4}\)

    I think then you're ready to isolate \(m\).

    Isolation means making the variable as the subject on one side and having a constant on the other.

    Add 7m to both sides then subtract both by 4.

    Make the 'm' alone, and sad. Make the 'm' letter sad to be alone on one side of the equation! But look, you start out with x gas. You use 3/4ths of it, which is .75x. Now you have x - .75x. Then you add 10! So it's x - .75x + 10 = 0 and solve for 'm'. Simple.
