Question

5x+7y-50=0
7x+5y-46=0

find x or y pls​

Answer 1

Answer:

by elemination method

7(5x+7y) = 50 : 35x + 49y = 50 _ eq1

5(7x+5y) = 49 : 35x + 25y = 46 _ eq2

35x+49y = 50

- 35x+25y = 46

= 00 +24y = 4

y = 4/24

y = 1/6

Y = 0.16

when we put the value of Y in eq 2 we ll get the value of x

35x+25×1/6 = 50

= 35x = 50×6/25

= 35x = 12

= x = 12/35

= x = 0.34
