Im confused 7/10=3/x+1?

Question

so
7/10= 3/x+1

Answer 1

7/10 = -3/10 +10/10
x= 10

Answer 2

x should equal 23/7
Try solving it as a proportion. Cross multiply. Multiply the numerator of one fraction to the denominator of the other: 7 times (x+1) and 3 times 10. Then set them equal to each other. You should end up with something like this:

7(x+1)=3(10)

Just solve it like a regular equation.

7x+7=30
7x=23
x=23/7

Answer 3

7/10= 3/x+1

First, isolate the term with the variable, x:

7/10 - 1 = 3/x
-3/10 = 3/x

Cross-multiply:
-3x = 3 x 10
-3x = 30

Divide:

-3x/(-3) = 30/(-3)
x = -10

Check:

7/10 = 3/(-10) + 1
7/10 = -3/10 +1
7/10 = 7/10

Answer 4

First multiply both sides of the equation by 10. This will eliminate some fraction. You get 7 = 30/x + 10
Subtract 10 on both sides. you get -3 = 30/x
Write it as a proportion. you get -3/1 = 30/x.
Cross multiply. you get -3x = 30. And x = -10.

Answer 5

7/10 = 3/(x+1)
7 = 30/(x+1)
7(x+1) = 30
7x +7 = 30
7x = 23
x = 23/7
x = 3 2/7

-----------------------------
7/10 = (3/x) + 1
7/10 -1 = 3/x
-3/10 = 3/x
-3 =30 /x
-3x =30
x = -10

Answer 6

these are equivalent fractions. The cross multiplication of equivalent fractions are equal. Example 2/4=5/10
Cross multiply and you get 20=20. Do the same with your problem and get 7x+7=30. Solve for x.

Answer 7

If the denominator is (x+1) then,

7/10=3/(x+1)
or, 7x+7=30
or, 7x=23
or, x=23/7


If the denominator is x then,

7/10=(3/x)+1
or, (7/10)-1=3/x
or, -3/10=3/x
or, x= -10

Thats the solution.

Answer 8

Cross multiply: 7(x+1)=10(3) and solve --> 7x + 7 = 30 -->
7x = 23 --> x = 23/7.

Answer 9

firstly, pls clear this;

(3/x) + 1 or 3 / (x+1)

if; (3/x) + 1 = 7/10

3/x = - 3/10

x = - 10

if; 3 / (x+1) = 7/10

x+1 = (3*10)/7

x = (30/7) - 1

x = 23 / 7

Answer 10

7/10 = 3/x+1
7x + 7 = 30
7x = 30 - 7
7x = 23
x = 23/7
x =3 2/7
