Question

X + 11y = 1
8x + 13y = 2​

Answer 1

Step-by-step explanation:

2×(x+11y)=8x+13y

=>6x=9y

=>x=1.5y

x+11y=1

=>12.5y=1

=>y=10/125

=>y=2/25

=>x=1.5×2/25

=>x=3/25

Answer 2

$let \: x + 11y = 1 \: as \: equation \: 1$

$and \: 8x + 13y = 2 \: as \: equation \: 2$

$subtract \: eq1 \: from \: eq2$

$8x + 13y - (x + 11y) = 2 - 1$

$8x - x + 13y - 11y = 1$

$7x + 2y = 1$

$x = \frac{1 - 2y}{7} \: and \: y = \frac{1 - 7x}{2}$
