1/5x + 1/2y = - 14 and 1/10x - 1/8y = 8


Sagot :

Assuming that the x and the y are on the numerators:
x/5 + y/2 = -14
x/10 - y/8 = 8

Multiply the first equation by 1/2  and subtract from the second equation
x/10 + y/4 = -7
x/10 - y/8 = 8

-3y/8 = 15
y = -40

substituting the value of y to the first equation
x/5 + y/2 = -14
x/5 - 40/2 = -14
x/5 - 20 = -14
x/5 = 6
x = 30

Hope this helps :)
