C)2bx - c/3 = bx/2 - c/3
2bx - bx/2 = - c/3 + c/3
4bx/2 - bx/2 = 0
3bx/2 = 0
3bx = 0.2
3bx = 0
bx = 0/3
bx = 0 ................ b ou x ou bx = 0
=========================================
d)
1 - x/a = 1 + xb
1 - 1 = xb + x/a
0 = axb/a + x/a
0 = axb+x/a
0.a = axb+x
0 = axb+x
axb = - x
ab = -x/x
ab = - 1
==============================
e)
m/n + n/m . (m²/nx+n²/mx) = 1
m/n + n/m.m²/nx + n/m.n²/mx = 1
m/n + m²n/mnx + n³/m²x = 1 multiplico todos por m²nx
m²nx.m/n + m²nx.m²n/mnx + m²nx.n³/m²x = m²nx
m³x + m³n + n^{4} = m²nx
m³x+m³n+n^{4}-m²nx = 0
