Use the substitution method to solve the system of equations. Please help me get this question right
vaieri [72.5K]

Answer:  B (2,1)

You know what y is (x-1) so you substitute that for y in the other equation.

3x+ ((4)(x-1))=10

3x+4x-4=10

7x=14

x=2

Then put x=2 into y=x-1

y=2-1

y=1

Joshua can purchase tile at one store for $0.99 per tile but he he will have to rent a tile saw for $25 at another store he can
natita [175]

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
