Answer:

Step-by-step explanation:

2X + 12=13x - 2x + 5

2x-11x = 5-12

-9x = -7

X = 7/9

What is the value of z in the equation 2(4z − 3 − 1) = 166 − 46?

shepuryov [24]

Refine $2(4z-3-1)$

$= 2(4z-4)$

Refine : $166 - 16 = 120$

therefore:

$2(z-4) = 120$

Divide both sides by 2 :

$\frac{2(z-4)}{2} = \frac{120}{2}$

$4z-4 = 60$

add 4 to both sides:

$4z-4+4 = 60+4$

$4z = 64$

Divide both sides by 4 :

$\frac{4z}{4} = \frac{64}{4}$

$z = 16$

hope this helps!
