Question

15 -(-7x + 6 ) = 7 - (4x + 9

Answer 1

Respuesta:

$\times = - 1$

Explicación paso a paso:

$15 - ( - 7 \times + 6) = 7 - (4 \times + 9)$

$15 + 7 \times - 6 = 7 - 4 \times - 9$

$9 + 7 \times = - 2 - 4 \times$

$7 \times + 4 \times = - 2 - 9$

$11 \times = - 11$

$\times = - 11 \div 11$

$\times = - 1$
