Word problems are usually linguistic problems because once you figure out what is being asked the math is normally routine. Let's try to rewrite the word problem as mathematical expressions.

x=mass of Pisa in tons
x+557=great pyramid
x-95=2695 (mass of Stonehenge)
2(x+557)=greater pyramid

Let's solve for x by using the equation x-95=2695:
x-95=2695
x=2695+95=2790

Now let's use our value for x to substitute and solve our problem.
2(x+557)=greater pyramid
2(2790+557)=greater pyramid
6694 tons = greater pyramid

Did we get it right?
