Of : 1/5 x + 1/8 y = 1 1/2 x − 1/3 y = 1

x = 75 and y = -72

Step-by-step explanation:

It is given that,

1/5 x + 1/8 y = 1   (1)

1/2 x − 1/3 y = 1  (2)

To find the solutions of the system of equations

Step 1: eq(1) * 5 ⇒

x + 5/8y = 5  (3)

Step 2:  eq(2) * 2 ⇒

x - 2/3y = 2  (4)

Step 3: eq(3) - eq(4) ⇒

x + 5/8y = 5  (3)

x - 2/3y = 2  (4)

0 +(5/8 - 2/3)y = 3

 -1/24 y = 3

y = -24*3 = -72

Step 4: Substitute the value of y in eq(1)

1/5 x + 1/8 y = 1   (1)

1/5 x + 1/8 (-72) = 1   (1)

1/5 x  - 24 = 1

1/5 x = 25

x = 5*25 = 75

Therefor x = 75 and y = -72

Step-by-step explanation:

I am guessing that your two equations are

(1) ⅕x + ⅛y = 1

(2) ½x - ⅓ y = 1

To get rid of fractions, I would multiply each equation by the least common multiple of its denominators.

We can solve this system of equations by the method of elimination.
