Question

x upon 2+3y upon 4= - 5 upon 2

Answer 1

x/2 + 3y/4= -5/2
(2x+3y)/4 = -5/2
(2x+3y) = (-5/2) × 4
2x+3y = -10
This is your equation

Answer 2

Answer :

x / 2 + 3y / 4 = -5 / 2
x / 2 + 3y × 1 / 4 = -5 / 2
x / 4 ( 2 + 3y ) = -5 / 2
x / 8 + 12 y = -5 / 2

By cross multiplication

2x = -5 ( 8+ 12 y )
2x = -40 + 60y
2x = 20 ( -2 + 3y )
x = 20 ( -2 + 3y ) / 2
x = 10 ( -2 + 3y )
x = -20 + 30y
x = 30y -20

Hope you got your answer.

Best of luck for your future !!!
