Sagot :
Answer:
12, 6
Step-by-step explanation:
we have two equations
x + y = 18 .... . (i)
and x = 2y .... .(ii)
substituting the value of x from eq. (ii) in eq. (i)
2y + y = 18
3y = 18
y = 6
putting this value if y in equation (ii) to get x
x = 2 × 6
= 12
therefore,
(12, 6) is the solution to the system of equations
x = 2y
2y + y = 18 x + y = 18
3y =18 x + 6 = 18
y = 6 x = 12
(12,6)
2y + y = 18 x + y = 18
3y =18 x + 6 = 18
y = 6 x = 12
(12,6)
