If x = 2y + 3 and 3x = 7 – 4y, what does x equal?

Step-by-step explanation:

x=2y+3

3x=7-4y

Rearrange the numbers so they compare,

x=2y+3

3x=-4y+7

Multiply the first equation by 2 (this is so the variable with y matches in both equations)

2x=4y+6

3x=-4y+7

Add the two equations together

2x=4y+6

+

3x=-4y+7

5x=13

Divide both sides by 5 to isolate x

x=13/5

Simply the equation

x=2 3/5

26

step-by-step explanation:

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
