Question

3 [2(x - 5)] = 6 + {x - (3 - 2x)}

Answer 1

3(2x-10)=6+(x-3+2x)
6x-30=3x+3
3x=27
x=9

Answer 2

3 [2(x - 5)] = 6 + {x - (3 - 2x)}

3 [2x - 10] = 6 + {x - 3 + 2x}

3 [2x - 10] = 6 + {3x - 3}

6x - 30 = 6 + 3x - 3

6x - 30 = 3 + 3x

6x - 3x = 3 + 30

3x = 33

x = 33/3

x = 11

Solución : 

x = 11
