2(2z - 4) = 3(z + 3)

3 answers

Expanding both sides of the equation, we get:

4z - 8 = 3z + 9

To isolate the variable z, we subtract 3z from both sides:

4z - 3z - 8 = 3z + 9 - 3z

Simplifying, we have:

z - 8 = 9

Adding 8 to both sides, we get:

z - 8 + 8 = 9 + 8

Simplifying, we have:

z = 17

Therefore, the solution is z = 17.
3(3x - 1) = 12
Expanding both sides of the equation, we get:

9x - 3 = 12

To isolate the variable x, we add 3 to both sides:

9x - 3 + 3 = 12 + 3

Simplifying, we have:

9x = 15

Dividing both sides by 9, we get:

9x/9 = 15/9

Simplifying, we have:

x = 5/3

Therefore, the solution is x = 5/3.
