how do you solve this? 1/3 + x = 3/4?

Question

please help.

1/3 + x = 3/4

you guys rock.
thank you all.

Answer 1

rewrite as

x = (3/4) - (1/3), note sign change, LCD is 12 or
x = (9/12) - (4/12)
x = 5/12.

Answer 2

Step #1 get a common denominator (12)

1/3=4/12
3/4=3/12

4/12 +x =9/12
subtract 4/12 from both sides
x= 5/12

Answer 3

To solve for x, you can subtract 1/3 from each side of the equation.

1/3 + x = 3/4.
1/3 + x - 1/3 = 3/4 - 1/3.
x = 3/4 - 1/3.
x = 9/12 - 4/12.
x = 5/12.

Answer 4

First: eliminate fractions - multiply the least common denominator with each term, which is 3(4) = 12

(12)(1/3)+(12)(x) = (12)(3/4)
12/3+ 12x = 36/4
4 + 12x = 9

SEc: combine "like" terms - subtract 4 from both sides (when you move a term to the opposite side, always use the opposite sign).

4 - 4+12x = 9 - 4
12x = 5

Third: isolate "x" - divide both sides by 12.

12x/12 = 5/12
x = 5/12

Answer 5

1/3 + x = 3/4

Just subtract 1/3 from both sides (to isolate x):
x = 3 / 4 - 1 / 3

That is the answer for the value of x, but it's an ugly expression and we need to simplify it into one rational fraction.

First, multiply each numerator by the OTHER denominator,
to get the new numerator:
(3*3) - (1*4)
so the new numerator is 9-4 or 5

Now, multiply the denominator, to get a new, common denominator:
4 * 3 is 12

So the fraction is:
= 5 / 12

(If you use this method, don't forget to reduce the fraction,
but here 5 and 12 have no common denominator, so that's the answer.)

Answer 6

subtract 1/3 from both sides

x=3/4 -1/3 to solve this you need both fractions to have the same denominator so find the lowest common denominator that these two numbers have (usually by multiplying them together so 3x4=12 so 3/4= 9/12 and 1/3= 4/12

so x= 9/12-4/12

x=5/12

Answer 7

1/3 + x = 3/4
==>subtract 1/3 from both sides
x = 3/4 - 1/3
==> get common denominator of 12 on right sides
x = 9/12 - 4/12
==> subtract four-twelfths from nine-twelfths
x = 5/12 ... ANSWER

Answer 8

1/3 + x = 3/4

first multiply both sides by 3*4 to get rid of the fractions

(1/3 + x)*3*4 = 3/4*3*4

4+12x=9

subtract four from both sides

12x=5

divide both sides by 12

x=5/12

Answer 9

x= -1/3+3/4= 5/12
x= 5/12

Answer 10

x=(3/4)-(1/3)=(9-4)/(12)
x=5/12
