i don’t how to use the mathway’s problem solver.
2log(3x-2)-log(x+1)=1+log(2)
all you have to do is to solve for x

The gateway arch in St. Louis was constructed using the hyperbolic cosine function. The equation used for construction was y= 693.8597- 68.7672 cosh0.0100333x,
-299.2239 is less then or equal to x which is less then or equal to 299.2239
where x and y are measured in feet. Cross sections of the arch are equilateral triangles, and (x,y) traces the path of the centers of mass of the cross-sectional triangles. For each value of x, the area of the cross-sectional triangle is A=125.1406cosh0.0100333x

(a) How high above the ground is the center of the highest triangle? (at ground level y=0)

(b) What is the Height of the arch?

(c) How wide is the arch at ground level?
