Question

(iii) 3x - 5y=16; x-3y=8​

Answer 1

Answer:

2 is answer I thunk

Step-by-step explanation:

5+3 and x + y =16

8 and x + y =16

x+y = 16/8

x+y=2

Answer 2

Step-by-step explanation:

★ Given that:

Equation (i):→ 3x - 5y = 16

→ 3x = 16 + 5y

→ x = (16 + 5y)/3

Equation (ii):→ x - 3y = 8

→ x = 8 + 3y

Comparing both the equation:

→ (16 + 5y)/3 = 8 + 3y

→ 16 + 5y = 3(8 + 3y)

→ 16 + 5y = 24 + 9y

→ 5y - 9y = 24 - 16

→ - 4y = 8

→ y = 8/-4

→ y = - 2

∴ We get the value of y = - 2

Substituting the value of y in Equation (i) or Equation (ii):

→ x = (16 + 5 × - 2)/3

→ x = (16 - 10)/3

→ x = 6/3

→ x = 2

Or,

→ x = 8 + 3 × - 2

→ x = 8 - 6

→ x = 2

∴ We get the value of x = 2

★ Verification:

We have to verify both the equation by putting the value of x and y:

Equation (i):→

➼ 3x - 5y = 16

➼ 3(2) - 5(-2) = 16

➼ 6 + 10 = 16

Verified

Equation (ii):→

➼ x - 3y = 8

➼ 2 - 3(-2) = 8

➼ 2 + 6 = 8

Step-by-step explanation:

Answer:

Answer:

Value of x = 2

And value of y = - 2
