Question

Află termenul necunoscut. (8 x 5) –x = 80 – 10 x 6​

Answer 1

8×5 - x = 80 - 10×6

40 - x = 80 - 60

40 = 20 + x

x=20

Answer 2

$\bf \: \green {(8 \times 5) - x = 80 - 10 \times 6} \\ \bf \: \green{40 - x = 80 - 10 \times 6} \\ \bf \: \green{40 - x = 80 - 60} \\ \bf \green{40 - x = 20} \\ \bf \green{x = \frac{40}{20} } \\ \bf \green{x =20}$
