Question

es con procedimiento me pueden ayudar ​

Answer 1

Respuesta:

$3(2x - 5) = 45 + 4x \\ 6x - 15 = 45 + 4x \\ 6x - 4x = 45 + 15 \\ 2x = 60 \\ x = \frac{60}{2} \\ x = 30$

$5 + 2(x - 4) = 6x - 9 \\ 5 + 2x - 8 = 6x - 9 \\ 5 - 8 + 9 = 6x - 2x \\ 6= 4x \\ \frac{6}{4} = x \\ \frac{3}{2} = x$

$5x - 9 = 3( x - 2) \\ 5x - 9 = 3x - 6 \\ 5x - 3x = 9 - 6 \\ 2x = 3 \\ x = \frac{3}{2}$

$2x + 5 = 3x + 10 \\ 5 - 10 = 3x - 2x \\ - 5 = x$
