Question

100×3-[62×(8+17:17-23:23)]:4:a=238​

Answer 1

Răspuns:

A va fi înlocuit cu litera necunoscută X.

100×3-[62×(8+17:17-23:23)]:4:x=238

$300 - ((62 \times (8 + 1 - 1))) \div 4 \times \frac{1}{x} = 238$

$300 - (62 \times 8) \div 4 \times \frac{1}{x} = 238$

$300 - 496 \div 4 \times \frac{1}{x} = 238$

$300 - 124 \times \frac{1}{x} = 238$

$- \frac{124}{x} = 238 - 300$

$- \frac{124}{x} = 62$

$124 = 62x$

$62x = 124$

$x = 2$
