Question

24 z + 4 + 2z equals 3(10z-1

Answer 1

24z + 4 + 2z = 3(10z - 1)

Simplify.

24z + 4 + 2z = 30z - 30

Add like terms.

(24z + 2z) + 4 = 30z - 30

Simplify.

26z + 4 = 30z - 30

Subtract 4 from both sides.

26z = 30z - 30 - 4

Then, subtract 30z from both sides.

26z - 30z = -30 - 4

Simplify.

-4z = -34

Divide both sides by -4.

$\dfrac{\cancel{-4}\text{z}}{\cancel{-4}} = \dfrac{-34}{-4}$

Simplify;

z = $\bold{\dfrac{17}{2}}$

Answer 2

Step-by-step explanation:

24z+2z+4=30z-3.

==26z+4=30z-3. 4+3=30z-26z. 7=4z. 7/4=z
