Question

Solve the following simultaneous equation :

3x + 8y = 17

x + 10y = 13​

Answer 1

Answer:

3x + 8y =17 × 1

x + 10y =13 ×3

3x +8y = 17

3x +30y =39

(-) (-) (-)

___________

-22y = - 22

y = - 22/-22

y = 1

Sub the value in eg 1

3x +8y =17

3x +8(1) =17

3x =17 - 8

x = 9/3

x =3

Therefore x =3 and y =1
