Answer: 23/2 or 11.5
Step-by-step explanation:
x - 10 = (x - 7) / 3
3 (x - 10) = x - 7
3x - 30 = x - 7
3x - x = 30 - 7
2x = 23
x = 23/2 answer...
change it into decimal form
x = 11.5 answer...
note: 23/2 or 11.5 both could be the answers
hope that helps...
Answer:
x = 23/2 or 11.5
Step-by-step explanation:
Step 1: Multiply both sides by 3.
- [tex]3(x-10)= \frac{x-7}{3} *3[/tex]
- [tex]3x - 30 = x - 7[/tex]
Step 2: Subtract x from both sides.
- [tex]3x-30-x=x-7-x[/tex]
- [tex]2x-30=-7[/tex]
Step 3: Add 30 to both sides.
- [tex]2x-30+30=-7+30[/tex]
- [tex]2x=23[/tex]
Step 4: Divide both sides by 2.
- [tex]2x/2 = 23/2[/tex]
- [tex]x = 23/2 = 11.5[/tex]
Therefore, x = 23/2 or 11.5.
