What is the value of x?<br><br> 6(x-4)=10
Mrac [35]

Answer:

  • \boxed{\sf{x=\dfrac{17}{3}=5.6 }}

Step-by-step explanation:

Use a distributive property.

<u>Distributive property:</u>

\Longrightarrow: \sf{A(B+C)=AB+AC}

⇒ 6(x-4)=10

<u>First, divide by 6 from both sides.</u>

⇒ 6(x-4)/6=10/6

<u>Solve.</u>

⇒ x-4=5/3

<u>Add by 4 from both sides.</u>

⇒ x-4+4=5/3+4

<u>Solve.</u>

5/3+4

4*3/3+5/3

4*3+5/3

4*3=12

12+5=17

x=17/3

<u>Dividing is another option.</u>

17/3=5.6

<u>x=17/3=5.6</u>

  • <u>Therefore, the final answer is x=17=5.6.</u>

I hope this helps you! Let me know if my answer is wrong or not.
