Consider the equation below. log4 (x+3) = log2 (2+x). Which system of equations can represent the equation?

Using: loga b = log b / log a

1) a=x+3, b=4 → y1=log4 (x+3) → y1 = log (x+3) / log 4

2) a=2+x, b=2 →y2=log2 (2+x) → y2=log (2+x) / log 2

Answer:

y1=log (x+3) / log 4, y2 = log (2+x) / log 2
