Answer:
There are three unknowns x,y and z. You need three equations.
From 4th equation you get x=2-y-z. substitute this value of x in equation 1
2-y-z+2y+3z=14
y+2z=12 equation 5
Similarly put x=2-y-z in equation 2
5(2-y-z)+8y,+11z=54
10-5y-5z+8y+11z=54
3y+6z=44 equation 6
With equation,5 and,6 you will get values of y and z. Then from any equation you will get the value of x
