Question

А:3=60:12. 703*19-х=39. Х:12=211-109. х:24=256

Answer 1

1) а=15
2) х= 13396
3)х= 1224
4)х= 10.6

Answer 2

A / 3 = 60 / 12
a / 3 = 5
a = 5 * 3
a = 15

703 * 19 - x = 39
13357 - x = 39
13357 - 39 = 13318
x = 13318

x / 12 = 211 - 109
x / 12 = 102
x = 102 * 12
x = 1224

x / 24 = 256
x = 256 * 24
x = 6144
