Answer:

1) 10

2) 40

3) 33

Step-by-step explanation:

1) Let the unknown number = x

=> 5x + 7 = 57

=> 5x = 57-7 = 50

=> x =50/5 = 10

=> x=10

2) Let the unknown number = y

=> 1/4 of y = 3 + 7 = y/4 = 10

=> y = 10 * 4 = 40

=> y = 40

3) Let the unknown number = z

=> 51 - z = z - 15

=> z + z = 51 + 15 = 2z = 66

=> z = 66/2 = 33

=> z = 33
