Question

What is the value for x in the proportion x+8/5x- 2=3/8?

Answer 1

Solve for x:
-2+(13 x)/5 = 3/8
Put the fractions in -2+(13 x)/5 over a common denominator.
Put each term in -2+(13 x)/5 over the common denominator 5: -2+(13 x)/5 = (-10)/5+(13 x)/5:
(-10)/5+(13 x)/5 = 3/8
Combine (-10)/5+(13 x)/5 into a single fraction.
(-10)/5+(13 x)/5 = (-10+13 x)/5:
1/5 (-10+13 x) = 3/8
Multiply both sides by a constant to simplify the equation.
Multiply both sides of (13 x-10)/5 = 3/8 by 5:
(5 (13 x-10))/(5) = 5×3/8
Express 5×3/8 as a single fraction.
5×3/8 = (5×3)/8:
(5 (13 x-10))/5 = (5×3)/8
Cancel common terms in the numerator and denominator of (5 (13 x-10))/5.
(5 (13 x-10))/5 = 5/5×(-10+13 x) = -10+13 x:
-10+13 x = (5×3)/8
Multiply 5 and 3 together.
5×3 = 15:
13 x-10 = 15/8
Isolate terms with x to the left hand side.
Add 10 to both sides:
13 x+(-10+10) = 15/8+10
Look for two terms that sum to zero.
-10+10 = 0:
13 x = 15/8+10
Put the fractions in 15/8+10 over a common denominator.
Put 15/8+10 over the common denominator 8. 15/8+10 = 15/8+(8×10)/8:
13 x = 15/8+(8×10)/8
Multiply 8 and 10 together.
8×10 = 80:
13 x = 15/8+80/8
Add the fractions over a common denominator to a single fraction.
15/8+80/8 = (15+80)/8:
13 x = (15+80)/8
Evaluate 15+80.
15+80 = 95:
13 x = 95/8
Solve for x.
Divide both sides by 13:
x = 95/(8×13)
Multiply 8 and 13 together.
8×13 = 104:
Answer: |
| x = 95/104

Answer 2

@ zkrup bro i think ur ans is nt appropriate.....

we will go for cross multiplicatiom
i.e
8x+64=15x-6
70=7x
x=10

Answer 3

10 is satisfying this equation
