Question

X + 2y = 8 , 3 X + 5 Y = 6​

Answer 1

Answer:

x=2

y=3

Step-by-step explanation:

equ. 1 ×3

equ.1 -equ.2

3x+6y=9

-3x-5y=-6

---------------

y=3 ---------------------- 3

substitute y=3 in 1

x+6=8

x=8-6

x=2 -------------------------2

Answer 2

X + 2Y = 8

X = 8 - 2Y --------- equation 1

3X + 5Y = 6

Substituting the value of X from equation 1

3(8-2Y) + 5Y = 6

24 - 6Y + 5Y = 6

24 -Y = 6

24 - 6 = Y

Y = 18

Substituting the value of Y in equation 1

X + 2(18) = 3

X + 36 = 3

X = -33
