You have 3c (3 times her cousins age) -4 (4 less than)
Answer:
C. None of the above.
Step-by-step explanation:
x − (−x) + y
x + x + y
= 2x + y.
here,
2x-6y= -12
2(x-3y)= -12
x-3y = -6...........eq1
x+2y=14............eq2
we can subtract the above two given equations
we get,

___________

so,
y=4
now to find the value of x we have to substitute the value of y in any of the above two equations, I choose eq2
we get,

<h3>so,</h3><h3> x=6,y=4</h3>
