Question

144-(х:11+21)×5=14 решите пж

Answer 1

144-(x:11+21)*5=14
(x:11+21)*5=14+144
(x:11+21)*5=158
x:11+21=158:5
x:11+21=31,6
x:11=31,6-21
x:11=10,6
x=10,6*11
x=116,

Answer 2

$144 - (x \div 11 + 21) \times 5 = 14 \\ 144 - ( \frac{x}{11} + 21) \times 5 = 14 \\ 144 - ( \frac{5x}{11} + 105) = 14 \\ 144 - \frac{5x}{11} = 14 \\ 39 - \frac{5x}{11} = 14 \\ 429 - 5x = 154 \\ - 5x = 154 - 429 \\ - 5x = - 275 \\ x = 55$
