Answer
Our two equations are:
+=16(1)
=55(2)
Rewriting equation (1) in terms of just = something, we get:
=16−
Substituting this into equation (2) leaves us:
(16−)=55
16−2=55⟹=5 or 11
which can be easily seen by factoring or using the quadratic formula. It follows that =11|=5 and =5|=11.
Thus your solutions in terms of (,) are (5,11) and (11,5).

Answer:
x=2
Step-by-step explanation:
8x+4=20
Subtract 4 from each side
8x+4-4 = 20-4
8x =16
Divide by 8
8x/8 = 16/8
x=2
