Respuesta:
x = 225/28
Explicación paso a paso:
Planteamiento:
(4x/3) + (7/2) = -4 + (2x/5)
Desarrollo:
(2/2)(4x/3) + (3/3)*(7/2) = -20/5 + (2x/5)
(8x/6) + (21/6) = (-20+2x)/5
(8x+21)/6 = (-20+2x)/5
5(8x+21) = 6(-20+2x)
5*8x + 5*21 = 6*-20 + 6*2x
40x + 105 = -120 + 12x
40x - 12x = -120 - 105
28x = -225
x = -225/28
