I am having dificulty solving logirithms once I put them in exponential form and vice versa. Here is the question I am confused on LOGx 16=4/3
how do we solve the intersection pt (x,y) of d following equations/lines

15x + 25y >= 375
18x + 12y >= 200
these three lines will intersect at a point, wha
