Hi!

$(2)/(3)=(x)/(12)$

$(x)/(12)=(2)/(3)$

$(12x)/(12)=(2*12)/(3)$

$(12x)/(12)=x$

$(2*12)/(3)=8$

$Answer---->x=8$

Explanation: First you had to switch sides to the problem. Then multiply by 12 from both sides. And simplify by 12x/12=8 or 2*12/3=8. And the answer should be x=8 is the right answer. Hope this helps! Thank you for posting your question at here on Brainly. And have a great day. -Charlie

8 is the answer to your question.

Navor has $800 and is spending $30 per week. Rashid has $150 and is saving $20 per week. In how many weeks will Nabor and Rashid have the same amount of money?

Answers

They will have the same amount of money at week 13 with $410 for each of them

-------------------------------------
Define x :
-------------------------------------
Let x be the number of weeks needed.

-------------------------------------
Navor :
-------------------------------------
Navor has $800 and is spending $30 per week:
800 - 30x

-------------------------------------
Rashid :
-------------------------------------
Rashid has $150 and is saving $20 per week:
150 + 20x

-------------------------------------
Solve x:
-------------------------------------
800 - 30x = 150 + 20x
50x = 800 - 150
50x = 650
x = 13

--------------------------------------------------------------------------------------------------------
Answer: They will have the same amount of money after 13 weeks.

Solve x: 3x-7 = 5x+13
Solve x: 7-3x = 5x+13

Answers

first you need to combine like terms
7-3x= 5x+13
step 1 add 3x
7=8x+13
step 2 subteact 13
-6=8x
step 3 divide both sides by two
x=-3/4

1.
Since 5x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 5x from both sides.
3x−7−5x=13

Add 3x and −5x to get −2x.
−2x−7=13

Move -7 to the right hand side of the equation.
−2x=7+13

Add 7 and 13 to get 20.
−2x=20

Divide each term in the equation by −2.

x=−10

2.
Since 5x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 5x from both sides.
7−3x−5x=13

Add −3x and −5x to get −8x.
7−8x=13

Move 7 to the right hand side of the equation.
−8x=−7+13

Add −7 and 13 to get 6.
−8x=6

Divide each term in the equation by −8.

x=−3/4
