Question

hi guys i need help for this

3/4x - 1/8x =5

how do i solve it?

Answer 1

Treat the expression to the left of the equals sign like a subtraction problem because it is.
3/4x and 1/8x have a common denominator of 8x.
4x goes into 8x twice so multiply 2 times 3. Your new fraction is 6/8x.
8x goes into 8x once and 1 times 1 is 1. Your new fraction is 1/8x.
6/8x - 1/8x is 5/8x .
Now you have 5/8 x = 5
Divide both sides by 5/8.
5/8 divided by 5/8 is 1 so 1x is on the left of the equals sign.
5 divided by 5/8 is calculated by multiplying 5/1 by the inverse of 5/8 which is 8/5.
5/1 times 8/5 = 40/5
So 1x = 40/5 and that can be reduced.
x = 8.

Answer 2

Here's how you solve this equation:

1. First, to subtract 1/8x from 3/4x, convert the 3/4x, so 3/4 = 6/8,
2. Now you have: 6/8x - 1/8x = 5
3. Simplify: 5/8x = 5
4. Divide/ x/5/8 = 5/5/8
5. Simplify: x = 5/(5/8)
6. Your answer will come out to be: x=8.

Answer 3

If the eq is 3/(4x) - 1/(8x) = 5, Multiply each side by x→
3/4 -1/8 = 5x = 5/8→ x = 1/8

If the eq is (3/4)x - (1/8)x = 5, combine the 2 on the left:
(5/8)x = 5 then divide each side by 5: (1/8)x = 1→ x = 8

Enter your eq carefully so it won't be ambiguous.......

Answer 4

8

Answer 5

Take 3/4x and subtract 1/8x to get 5/8x.
Then multiply 5 by 8/5 to get 40/5
Then simplify to get X=8

Answer 6

First you convert the two fractions so that they have the same denominator. (3/4=6/8) Then you add them together, just like any normal fractions. After that, you multiply both sides of the equation by the denominator, and divide both sides by the numerator. That should leave just x = something.

Answer 7

first multiply the whole equation by 8, so it becomes:

6x - 1x = 40

the add (subtract like terms)

5x = 40

then divide by 5

x = 8
