Answer 2

Answer:

5 + 6y = 13 ... (1)

x

3 + 4y = 7 ... (2)

x

Substituting 1/x as z in the above equations,

Therefore,

5z + 6y = 13 ... (3)

and

3z + 4y = 7 ...(4)

Multiplying equation (3) by 3,

15z + 18y = 39 ... (5)

Multiplying equation (4) by 5,

15z + 20y = 35 ... (6)

Subtracting (6) by (5),

-2y = 4

Therefore, y = -2

Substituting y= -2 in (4),

3z + 4(-2) = 7

3z - 8 = 7

3z = 7 + 8

3z = 15

z = 5

Resubstituting, z = 1/x

5 = 1

x

Therefore,

x = 1

5

Therefore, Solution of the simultaneous equations is (x, y) = (1/5, -2)
