Answer:
Step-by-step explanation:
Use a distributive property.
<u>Distributive property:</u>

⇒ 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>
