Question

10x + y = 14000
9x + 6y = 13500​

Answer 1

Answer:

x=1382.35, y=176.47

Step-by-step explanation:

let

10x + y = 14000 be the 1st equation

9x + 6y = 13500 be the 2nd equation

By solving 1 and 2

equation 1 * 2 : 20x + 2y = 28000

equation 2/3 : 3x + 2y = 4500

(-) (-) (-)

17x = 23500

x = 23500/17

x = 1382.35

put x = 1382.35 in equation 1

10(1382.35) + y = 14000

13823.52 + y = 14000

y = 14000 - 13823.52

y = 176.47

Answer 2

x=1382.4

y=176
