Question

6z-7=2z-2 can't figure it out

Answer 1

Answer: z = 5/4

Step-by-step explanation: First simplify the equation by subtracting 2z from both sides and adding 7 to both sides to get 4z = 5.

Step by step below

6z -7 = 2z -2

-2z -2z

4z -7 = -2

+7 +7

4z = 5

Now divide both sides by 4 to get z = 5/4

4z/4 = 5/4

z = 5/4

Hope this helps!

Answer 2

`\huge\boxed{z=(5)/(4)=1(1)/(4)=1.25}`

Explanation:

`6z-7=2z-2\qquad|\text{add 7 to both sides}\\\\6z-7+7=2z-2+7\\\\6z=2z+5\qquad|\text{subtract}\ 2z\ \text{from both sides}\\\\6z-2z=2z-2z+5\\\\4z=5\qquad|\text{divide both sides by 4}\\\\(4z)/(4)=(5)/(4)\\\\\boxed{z=(5)/(4)}`
