Question

1. 3x – 2[x – 2(x – 3)] = 13.​

Answer 1

Answer:

25

Step-by-step explanation:

$\implies$ $\sf{3x-2[x - 2(x-3)] = 13 }$

$\implies$ $\sf{ 3x - 2[ x -2x+6] = 13}$

$\implies$ $\sf{3x - 2x + 4x - 12 = 13 }$

$\implies$ $\sf{7x - 2x -12 = 13 }$

$\implies$ $\sf{5x - 12 = 13 }$

$\implies$ $\sf{ 5x = 13+12}$

$\implies$ $\sf{x= {\Large\frac{ 25 }{ 5}} }$

$\therefore$ $\boxed{\sf{ x = 5}}$

Answer 2

Step-by-step explanation:

3x - 2[ x - 2(x - 3) ] = 13

3x - 2[ x - 2x + 6 ] = 13

3x - 2[ -x + 6 ] = 13

3x + 2x - 12 = 13

5x = 13 + 12 = 25

x = 25/ 5 = 5

[x = 5]

I hope ur doubt is clear. : )
