ayuda es ecuación lineal

Answer 1

Respuesta:

$1)2x - x + 4 + 2 = 8 \\ x + 6 = 8 \\ x = 8 - 6 \\ x = 2 \\ \\ 2)3x + 1 - 2x = 4 - 3 \\ 3x - 2x = 1 - 1 \\ x = 0$

Explicación paso a paso:

$3)6 + 2x - 4 = x - 1 \\ 2 + 2x = x - 1 \\ 2x - x = - 1 - 2 \\ x = - 3$

$4) - 6 - 2x = - 3x - 6 \\ - 2x + 3x = - 6 + 6 \\ x = 0$

$5)x + x + 4 + 2 = 8 \\ 2x + 6 = 8 \\ 2x = 8 - 6 \\ 2x = 2 \\ x = 2 \div 2 \\ x = 1$

$6)2x + x + 5 - 5 = 6 \\ 3x = 6 \\ x = 6 \div 3 \\ x = 2$

$7)2x - x - 3 - 5 = 2 \\ x - 8 = 2 \\ x = 2 + 8 \\ x = 10$

8)

$2x + 2 - 1 - x = 2 \\ x + 1 = 2 \\ x = 2 - 1 \\ x = 1$

9)

$5x - 4 = 3x - 2 \\ 5x - 3x = - 2 + 4 \\ 2x = 2 \\ x = 2 \div 2 \\ x = 1$

10)

$2x - 5 + 1 + x = x - 6 \\ 3x - 4 = x - 6 \\ 3x - x = - 6 + 4 \\ 2x = - 2 \\ x = - 2 \div 2 \\ x = - 1$
