Question

4 x minus y equals to 5 and 5 Y - 4 x equals to 7 find X and Y​

Answer 1

Step-by-step explanation:

4x-y-5=0

5y-4x-7=0 => -4x+5y-7=0

x/-7(-1)(-5)(5) = y/-5(-4)(-7)(4) = 1/4(5)(-4)(-1)

x/7+24 = y/20+28 = 1/20-4

x/32 = y/48 = 1/16

taking, x/32 = 1/16

x = 1/16(32)

x = 2

Again, y/48=1/16

y=1/16(48)

y= 3

Hence, (x, y) = (2,3)
