Question

como se resuelve por favor con procedimiento 4(x₊3)₊x=9(x₊3)/2

Answer 1

4 (x + 3) + x = 9 (x + 3)/2

4x + 12 + x = (9x + 27)/2

5x + 12 = (9x + 27)/2

2 (5x + 12) = 9x + 27

10x + 24 = 9x + 27

10x - 9x = 27 - 24

x = 3

Solución : 

x = 3

VERIFICAMOS

4 (x + 3) + x = 9 (x + 3)/2

4 (3 + 3) + 3 = 9 (3 + 3)/2

4 (6) + 3 = 9 (6)/2

24 + 3 = 54/2

27 = 27

Listo!!!
