Answer:
The value of y is 
Step-by-step explanation:
we have
-----> equation A
-----> equation B
To eliminate the x-variable and find the value of y Multiply the equation A by -18/4 both sides or multiply the equation B by -4/18 both sides
I choice
Multiply the equation A by -18/4 both sides
![(-18/4)[4x+3y]=6*(-18/4)](https://tex.z-dn.net/?f=%28-18%2F4%29%5B4x%2B3y%5D%3D6%2A%28-18%2F4%29)
------> equation C
Adds equation B and equation C
