## anonymous one year ago What is the value of x in the equation 2(2x − 5 − 4) = 160 − 17? 40.25 62.25 80.25 143.0

1. anonymous

Start by combining like terms, like the -5 and -4, and the 160 and -17

2. anonymous

ok 2(2x-9)=153

3. anonymous

Okay, now divide both sides by 2

4. anonymous

2x-9=72.5?

5. anonymous

you mean distribute?

6. anonymous

Oh wait, you made a mistake when you subtracted the 17, it should have been 143

7. anonymous

8. anonymous

got confused.. ops

9. anonymous

So back to the beginning. 2(2x-5-4)=160-17

10. anonymous

You can reduce this to 2(2x-9)=143

11. anonymous

right

12. anonymous

So, without having to distribute the 2, since its already on the outside, you can just divide both sides by 2

13. anonymous

ok

14. anonymous

Now you can add nine to both sides to get the x term by itself

$2\left(2x-5-4\right)=160-17\quad :\quad x=\frac{161}{4}\quad \left(\mathrm{Decimal:\quad }x=40.25\right)$

16. anonymous

Yes, after you add the nine, divide both sides by 2 to get your final answer, 40.25

17. anonymous

ohhhh thankss guyss thanks for the explination

18. anonymous

turn up

What is the solution to the following equation? 2(3x − 7) + 18 = 10 1 3 5 6

20. DecentNabeel

$2\left(3x-7\right)+18=10\quad :\quad x=1$ 2(3x − 7) + 18 = 10 6x-14+18=10 6x+4=10 subtract 4 on both sides 6x-4+4=10-4 6x=6 x=1

21. DecentNabeel

are you understand @bby.nessa

22. anonymous

yea i understand thanks

just take every terms without x to the right side of equation to get the value of x it's simple first try your own then ask for explanation that's the way of learning.
