Question

me podria ayudar con esta tarea porfa es urgente

Answer 1

$9x + 3 = 5x - 1$

$9x - 5x = - 1 - 3$

$4x = - 4$

$x = \frac{ - 4}{4}$

$x = - 1$

9(-1) + 3 = 5(-1) - 1

-9 + 3 = -5 - 1

-6 = -6

$</p><p>7-8x=2x-3$

$- 8x - 2x = - 3 - 7$

$- 10x = - 10$

$x = \frac{ - 10}{ - 10}$

$x = 1$

7 - 8(1) = 2(1) - 3

7 - 8 = 2 - 3

-1 = -1

$</p><p>2x-6=16-9x$

$2x + 9x = 16 + 6$

$11x = 22$

$x = \frac{22}{11}$

$x = 2$

2(2) - 6 = 16 - 9(2)

4 - 6 = 16 - 18

-2 = -2
