How to solve ×+6y=13. 2×+y=15

x, y = 7, 1

Step-by-step explanation:

x+6y=13 (i)

2x+y=15 (ii)

We will apply substitute method.

From equation (i), we can get,

x+6y=13

or, x = 13 - 6y (iii)

Putting the value of x in equation (ii), we can get,

2x+y=15

or, 2 × (13 - 6y) + y = 15

or, 26 - 12 y + y = 15 [multiplying]

or, -11 y = 15 - 26 [Subtracting 26 from both the sides]

or, -11 y = -11

or, [(-11 y) ÷ (-11)] = [(-11) ÷ (-11)] [Dividing both the sides by -11]

or, y = 1

Therefore, the value of y = 1

Putting y = 1 in equation (iii), we get,

x = 13 - 6y

or, x = 13 - 6 × 1

or, x = 13 - 6

or, x = 7

Therefore, the value of x = 7.

x, y = 7, 1

answer: -1
