Question

3.x+5parax12.
8.y_9,para=3.
4.m+17,para m=7.

Answer 1

3 * 12 = 48
48 + 5 = 53

3 / 9 = 0,33...
8 * 0 33... = 2,66...7

OU

8 * 3 = 24
24 - 9 = 15

4 * 7 = 28
28 + 17 = 45

Answer 2

x = 12
3x + 5 = 3.12 + 5 = 36 + 5 = 41

y = 3
8y - 9 = 8.3 - 9 = 24 - 9 = 15

m = 7
4m + 17 = 4.7 + 17 = 28 + 17 = 45
