Question

2( 5 – 3x ) – ( - 4x + 7 ) = ( 8x + 11) – 4( 3x – 6 )

Answer 1

Respuesta:

x=16

Explicación paso a paso:

$2(5 - 3x) - ( - 4x + 7) = (8x + 11) - 4(3x - 6) \\ 2 \times 5 - 2 \times 3x + 4 \times - 7 = 8x + 11 - 4 \times 3x - 4 \times ( - 6) \\ 10 - 6x + 4x - 7 = 8x + 11 - 12x + 24 \\ 3 - 2x = - 4x + 35 \\ - 2x + 4x = 35 - 3 \\ 2x = 32 \\ 2x \div 2 = 32 \div 2 \\ x = 16$
