sineoko [7]

Add 2.2 to each side so 0.3z = 5.2 - 0.5z -0.8z
add 0.5z to each side so 0.8z = 5.2 - 0.8z
add 0.8z to each side so 1.4z = 5.2
divide each side by 1.4 so z = 3.71428571

I need some help please

gizmo_the_mogwai [7]

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

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

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

$= > 2x = 14$

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