Answer:
option C
Step-by-step explanation:
x = 3y + 1 equation(i)
2x + 4y =12 equation(ii)
First working for equation (ii)
substituting the value of x in equation (ii)
2(3y + 1) + 4y = 12
6y + 2 + 4y = 12
10y = 12 - 2
y = 10/10
y =1
now substitute the value of y in equation (i)
x = 3*1 = 1
x=3 + 1
x = 4
therefore , answer is (4,1)
