Question

find the value of x and y in the given system??​

Answer 1

Step-by-step explanation:

solve given equations

x/2 + y = 0.8

7/(x+ y/2) = 10

(x+2y)/2 = 0.8

x + 2y = 1.6 -----(1)

(2*7)/(2x+y)= 10

14/(2x + y) = 10

2x+y= 14/10

2x + y = 1.4 -----(2)

solve equ 1 and equ 2

2*equ 1 --- 2x + 4y = 3.2

2x + 4y - 2x - y = 3.2 - 1.4

3y = 1.8

y = 0.6

x + 2(0.6) = 1.6

x = 1.6 - 1.2

x = 0.4
