Question

Is z =9 a solution to 3z+8=25

Answer 1

Step by step:
3*9+8=25
(3*9)+8=25
27+8=25
35=25

Answer 2

No, z =9 isn't a solution to 3z+8=25

Explanation:

Let's see if it is...

`\sf 3z+8=25`

Subtract 8 from both sides:-

`\sf 3z+8-8=25-8`

`\sf 3z=17`

Divide both sides by 3:-

`\sf \cfrac{3z}{3}=\cfrac{17}{3}`

`\sf z=\cfrac{17}{3}\;\; or \;\; z=5.6666....`

Therefore, no z = 9 isn't a solution to 3z+8=25.
