Question

Descoperă numărul A din egalitatea : A÷8+32×9-36×4=187

Answer 1

a : 8 + 32 x 9 - 36 x 4 = 187
a : 8 + 288 - 144 = 187
a : 8 + 288 = 187 + 144
a : 8 + 288 = 331
a : 8 = 331 - 288
a : 8 = 43
a = 43 x 8
a = 344

Answer 2

$a \div 8 + 32 \times 9 - 36 \times 4 = 187$
$a \div 8 + 288 - 144 = 187$
$a \div 8 + 144 = 187$
$a \div 8 = 187 - 144$
$a \div 8 = 43$
$a = 43 \times 8$
$a = 344$
