Answer:
no solution
Step-by-step explanation:
this is considered no solution because first you have to simplify 10x-10x which equals 0 and since -8=0 is false its considered no solution.
hope that helped :)

Answer: the number of tiles will be 49
Step-by-step explanation:
Let x represent the number of tiles that Joshua can buy at either stores.
one store for $0.99 per tile but he he will have to rent a tile saw for $25. Let the total cost of buying x tiles in this store be y. Therefore
y = 0.99x + 25
At another store, he can buy a tile for $1.50 per tile and borrow a tile saw for free. Let the total cost of buying x tiles in this store be z. Therefore
z = 1.5x
To determine the number of tiles for which both costs will be the same, we will equate y to z. It becomes
0.99x + 25 = 1.5x
1.5x - 0.99x = 25
0.51x = 25
x = 25/0.51
x = 49
