Question

Resuelve las ecuaciones lineales

2x-4=5×+8

5(×+2) = 3(x+1)+9​

Answer 1

Respuesta:

$2x - 4 = 5x + 8 \\ 2x - 5x = 8 + 4 \\ - 3x = 12 \\ 3x = - 12 \\ x = \frac{ - 12}{3} = - 4$

$2( - 4) - 4 = 5( - 4) + 8 \\ - 8 - 4 = - 20 + 8 \\ - 12 = - 12$

Explicación paso a paso:

$5(x + 2) = 3(x + 1) + 9 \\ 5x + 10 = 3x + 3 + 9 \\ 5x - 3x = 12 - 10 \\ 2x = 2 \\ x = \frac{2}{2} = 1 \\ 5(1 + 2) = 3(1 + 1) + 9 \\ 5 \times 3 = 3 \times 2 + 9 \\ 15 = 6 + 9 \\ 15 = 15$

espero te sirva
