Question

(x-1):2=12:8



ayudaaaaaaaa :-(​

Answer 1

Respuesta:

$x = 4$

Explicación paso a paso:

$(x - 1) \div 2 = 12 \div 8$

$\frac{x - 1}{2} = \frac{12}{8}$

$\frac{8(x - 1)}{2} = 12$

$8(x - 1) = 12 \times 2$

$8(x - 1) = 24$

$8(x - 1) \div 8 = 24 \div 8$

$x - 1 = 3$

$x - 1 + 1 = 3 + 1$

$x = 3 + 1$

$x = 4$
