Question

conjunto solución 2(x+1)+3(x-2)=4(x+1)

Answer 1

Resolver.

2(x + 1) + 3(x - 2) = 4(x + 1)
2x + 2 + 3x - 6 = 4x + 4
5x - 4 = 4x + 4
5x - 4x = 4 + 4
x = 8

Respuesta.
x = 8

Comprobación.

2(x + 1) + 3(x - 2) = 4(x + 1)
2(8 + 1) + 3(8 - 2) = 4(8 + 1)
2* 9 + 3 * 6 = 4 * 9
 18  +   18   = 36
        36       = 36
