Question

What is the value of x in the equation 2(2x − 5 − 4) = 160 − 17?

40.25
62.25
80.25
143.0

Answer 1

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

Answer 2

ok 2(2x-9)=153

Answer 3

Okay, now divide both sides by 2

Answer 4

2x-9=72.5?

Answer 5

you mean distribute?

Answer 6

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

Answer 7

Then add nine to both sides, and divide by two, and you should have your answer

Answer 8

got confused.. ops

Answer 9

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

Answer 10

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

Answer 11

right

Answer 12

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

Answer 13

ok

Answer 14

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

Answer 15

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

Answer 16

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

Answer 17

ohhhh thankss guyss thanks for the explination

Answer 18

turn up

Answer 19

What is the solution to the following equation?

2(3x − 7) + 18 = 10

1
3
5
6

Answer 20

\[2\left(3x-7\right)+18=10\quad :\quad x=1\]
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

Answer 21

are you understand @bby.nessa

Answer 22

yea i understand thanks

Answer 23

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.
