    First divide a from both sides. then subtract b, now I would multiple both sides by -1 to get a nice positive c on the left side! We end up with \[c=-(\frac{ d-b }{ a})\]

    [distribute the a] ac - ab = d [add ab to both sides] ac = d + ab [divide both sides by a] c = (d + ab)/a can also be written as c = d/a + b

    Triangle problem: remember triangle area is \[ \frac{ Base * Height }{ 2 }\] Let's plug in what we know... \[Area 110m^2 = \frac{ base* 10m }{ 2 }\] Solve it and we get 22m!
