Question

Solve the simultaneous equations x + 6 y = 20 x + 2 y = 8

Answer 1

Answer:

x = 2

y = 3

Step-by-step explanation:

x + 6y = 20................equation 1

x + 2y = 8 ..................equation 2

Subtracting equation 1 and 2

x + 6y = 20

x + 2y = 8

(-)(-) (-)

4y =12

y = 3

Substitute y in equation 2

x +2(3) = 8

x + 6 = 8

x = 2

Answer 2

Subtract second from first
=> 4y = 12 => y=3
Putin any equation,
=> x= 2
