Question

10+3(x-1)=4x

5(x-3)=3(x+1)​

Answer 1

Respuesta:

1) X = -4

2) X = -6

Explicación paso a paso:

$10 + 3(x - 1) = 4x \\ 13(x - 1) = 4x \\ 13x - 13 = 4x \\ - 13 = 4x - 13x \\ - 13 = - 9x \\ - 13 + 9 = x \\ - 4 = x$

Ahí decimos que X = -4

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

Aquí X = -6
