## anonymous one year ago HELP ME UNDERSTAND What is the solution for the equation 4x − 10 = 2x? x = ___.

1. anonymous

@pooja195 can you help?

2. pooja195

Do you know what the first step would be?

3. anonymous

4. pooja195

ok so we have $\huge~\rm~4x=2x+10$ whats next?

5. anonymous

divide by 4?

6. pooja195

not quite we need to subtract the 2x $\huge~\rm~2x=10$ now we can divide by 2 $\huge~\rm~\frac{ 2x=10 }{ 2~~=2}$

7. anonymous

wouldnt it be x= 2 ?? and what about 4x?

8. pooja195

We subtracted the 2x from 4x because we need to ISOLATE x $\huge~\rm~2\div2=?$ $\huge~\rm10\div 2=?$

9. anonymous

x=5?

10. pooja195

yes :)

Henry's rocket is designed to launch to a height of 100 feet in the air. The measurements so far have the launch height (h) varying no more than 4 feet. Which inequality below represents this scenario? |h − 4| less than or equal to 100 |h + 4| greater than or equal to 100 |h − 100| less than or equal to 4< my answer |h + 100| greater than or equal to 4
