Explanation

To solve for x:

9x - 3 = 15

Add 3 to both sides:

9x = 18

Divide by 9:

x = 2

Now, substitute x into the second equation:

3x - 1 = 3(2) - 1

= 6 - 1

= 5

Explanation

To evaluate the expression, follow the order of operations:

Multiply 2 and 3: 2 × 3 = 6

Subtract 5 from 4: 4 - 5 = -1

Divide -1 by -1: -1 ÷ -1 = 1

Add 6 and 1: 6 + 1 = 7

"This is the best peach producing valley" 

Grammatically awkward. It should be:

 "This is the best peach-producing valley."

(Hyphenate "peach-producing" as it's a compound adjective.)

"I done matric in 2010" 

Incorrect verb form. It should be:

"I did matric in 2010"

("Done" is the past participle; here we need the simple past, "did.")

"This is an utensil" 

"An" is used before vowel sounds, not just vowels.

 The correct sentence is: "This is a utensil."

Because "utensil" starts with a 'yoo' sound, which is a consonant sound.

So, since all the options have errors, the correct choice is:

"None of these"
