3х + 5y=16
4 ч+6x = 2 O​

Answer 1

Answer:

HELLO DEAR

GM ♥

BY ELIMINATION METHOD

IM GOING TO ELIMINATE THE (X) TERMS

3X + 5Y = 16

6X + 4Y = 20

TAKING LCM = 6

NOW,

6X + 10Y = 32 (1)

6X + 4Y = 20 (2)

CHANING THE SYMBOLS OF (2) EQU.

6X + 10Y = 32

-6X - 4Y = -20

CANCELLING 6X & -6X

6Y = 12

Y = 2

SUBSTITUTING Y = 2 IN EQU.(1)

X = (32 - 10 x 2)/6

X = 12/6 , X = 2

THE VALUE OF X = 2 = Y

HOPE IT HELPS :)

Answer 2

1

$3x + 5y = 16$

$3x + y = 16 \div 5 \\ x + y = 16 \div 5 \div 3 \\xy = 1.0666$

2.

$4y + 6x = 20 \\ y + 6x = 20 \div 4 \\ y + x = 5 \div 6 \\ yx = 0.83333$

I hope this help you
