Question

1) x + 23 = 41;
2) 36 + y = 74;
3) 85 + z = 97;
4) x - 61 = 17;
5) 46 - y = 24;
6) 53 - z = 25;
7) m : 21 = 10;
8) 192 : n = 16;
9) k : 44 = 20.​

Answer 1

$x + 23 = 41 \\ x = 41 - 23 \\ x = 18$

$36 + y = 74 \\ y = 74 - 36 \\ y = 38$

$85 + z = 97 \\ z = 97 - 85 \\ z = 12$

$x - 61 = 17 \\ x = 17 + 61 \\ x = 78$

$46 - y = 24 \\ y = 46 - 24 \\ y = 22$

$53 - z = 25 \\ z = 53 - 25 \\ z = 28$

$m \div 21 = 10 \\ m = 21 \times 10 \\ m = 210$

$192 \div n = 16 \\ n = 192 \div 16 \\ n = 12$

$k \div 44 = 20 \\ k = 20 \times 44 \\ k = 880$
