solve each equation and check the solution 7/x+1/4=9/x​

Sagot :

Answer:

x = - 8

Step-by-step explanation:

Given rational algebraic equation:

(7/x) - (1/4) = (9/x)

Least common denominator (LCD): (4)(x)

Multiply each term by 4x:

(4x) [(7/x) - (1/4) = (9/x)] (4x)

28 - x = 36

Find the value of x:

28 - x = 36

28 - 36 = x

x = - 8

Check when x = -8:

(7/x) - (1/4) = (9/x)

7/(-8) - 1/4 = 9/(-8)

-7/8 - 1/4 = -9/8

LCD: 8

-7/8 - 2/8 = -9/8

-9/8 = -9/8 (True)
