Question

resuelve las siguientes sumas o restas de vectores​

Answer 1

Explicación:

1)

$5y + 3 = 11 + y \\ 5y - y = 11 - 3 \\ 4y = 8 \\ y = \frac{8}{4} \\ y = 2$

2)

$9x + 5x = 53 - 11 \\ 14x = 42 \\ x = \frac{42}{14} \\ x = 3$

3)

$7x - 5 = 4x + 7 \\ 7x - 4x = 7 + 5 \\ 3x = 12 \\ x = \frac{12}{3} \\ x = 4$

4)

$3x + 11 - 7x = 1 \\ - 4x = 1 - 11 \\ - 4x = - 10 \\ 4x = 10 \\ x = \frac{10}{4} \\ x = 2.5$

5)

$12x - 20 - 5x = 3x + 32 - x \\ 12x - 5x - 3x + x = 32 + 20 \\ 4x = 52 \\ x = \frac{52}{4} \\ x = 13$
