Answer 1

Two equtions to solve this problem:
T + S = 925 ➡️ S = -T + 925

4T + 6S = 4524

Substitute S = - T + 925 into 4T + 6S = 4524
4T + 6(-T + 925) = 4524
4T - 6T + 5,550 = 4524
-2T + 5,550 = 4524
-2T = - 1,026
T = 513

Substitute this answer into the first equation.
S = -T + 925
S = -513 + 925
S = 412

They sold 513 turkey sandwiches and 412 steak sandwiches.

Double check: 513 + 412 = 925
