Solve Linear 



In this app the questions are carefully graded from easy up to difficult in 29 steps.
Solve linear equations like:
x ± a = b x/a = b a/x = b ax ± b = c ax + b = cx + d a(x + b) = c a(x + b) = cx + d x − a = b(cx − d) a(b − x) = c(dx − e) a(b + x) − c(dx − e) − f = g x/a + b = c ax/b − c = d (ax − b)/c = d x/a + b = x/c x/a + b = c − x/d ax/b − c = dx/e (x − a)/b + (cx + d)/e = f (x + a)/b = (c − dx)/e − f ax/(bx − c) = d a/(bx + c) = d/x a/(x + c) + d/(x − e) = 0 a/(x − c) − d/(x − e) = f/(e − x)
