Answer:

a) -10

b) 7

Step-by-step explanation:

a) $2(x + 3) = x - 4$

$= > 2x + 6 = x - 4$

$= > 2x - x = - 4 - 6$

$= > x = - 10$

b) $4(5x - 2) = 2(9x + 3)$

$= > 20x -8 = 18x + 6$

$= > 20x - 18x = 8 + 6$

$= > 2x = 14$

$= > x = \frac{14}{2} = 7$

#9. Solve: 8x + 5 = 3x + 15 X = 4 x = 2 x = 20/11 x = 20

Jobisdone [24]

Answer:

x = 2

Step-by-step explanation:

8x + 5 = 3x + 15

8x - 3x + 5 = 3x - 3x + 15

5x + 5 = 15

5x + 5 - 5 = 15 - 5

5x = 10

5x / 5 = 10 / 5

x = 2
