Question

2(x+3x/4)=4200
(resuelto paso a paso)

Answer 1

2(x + 3x/4)=4200
2x+ 6x/4=4200
(8x+6x)/4=4200
14x= 4200 ×4
x= 16800/14
x =1200
Espero haberte ayudado

Answer 2

2(x+3x/4)=4200
2x + 6x/4 = 4200
(4 * 2x + 6x)/4 = 4200
8x + 6x = 4 (4200)
14x = 16800
x = 16800/14
x = 1200----respuesta

COMPROBAMOS.
2 (x + 3x/4) = 4200
2 (1200 + 3 (1200/4) = 4200
2 (1200 + 3600/4) = 4200
2 (1200 + 900)  = 4200
2 (2100) = 4200
4200 = 4200

La solución es correcta.
