Solving Formulas for a Different Variable

Take equations like A=(l)(w), then solve for the l or solve for the w.

AB
A = (b)(h) solve for b.b = A/h
A = (b)(h) solve for h.h = A/b
A = (b)(h) solve for A.A = bh
A = 1/2(b)(h) solve for b.b = 2A/h
A = 1/2(b)(h) solve for h.h = 2A/b
A=1/2(b1 + b2)(h) solve for b1.b1 = 2A/h - b2
A=1/2(b1 + b2)(h) solve for b2.b2 = 2A/h - b1
P=2l + 2w solve for l.l = (P - 2w)/2
P=2l + 2w solve for w.w = (P - 2l)/2
P=2l+2w find the matching formula.P = 2(l + w)
A=1/2(b1+b2)(h) solve for h.h = 2A/(b1 + b2)
SA=2lw + 2hw + 2lh solve for l.l = (SA -2hw)/(2w + 2h)
SA = 2lw + 2hw + 2lh solve for h.h = (SA - 2lw)/(2w + 2l)
SA = 2lw + 2hw + 2lh solve for w.w = (SA - 2lh)/(2l + 2h)
V = (l)(w)(h) solve for h.h = V/(lw)
V = (l)(w)(h) solve for w.w = V/(lh)
V = (l)(w)(h) solve for l.l = V/(wh)
d=(r)(t) solve for t.t = d/r
d= (r)(t) solve for r.r = d/t
y - y1 = m(x - x1) solve for m.m = (y - y1)/(x - x1)
F = (9/5)C + 32 solve for C.C = (5/9)(F - 32)
V = Bh solve for h.h = V/B
V = Bh solve for B.B = V/h
V = (1/3)(B)(h) solve for B.B = 3V/h
V = (1/3)(B)(h) solve for h.h = 3V/B
