Question

3 × х +50 =77 ; 100- 24 ÷ с=92. помогите решить уравнение пожалуйста

Answer 1

$1)3x + 50 = 77$
$3x = 77 - 50$
$3x = 27$
$x = 27 : 3$
$x = 9$
______________
$2)100 - 24 : c = 92$
$- \frac{24}{c} = 92 - 100$
$- \frac{24}{c} = - 8$
$8c = 24$
$c = 3$

Answer 2

3x + 50 = 77
3x = 77 - 50
3x = 27
x = 27 / 3
x = 9


100 - 24 / с = 92
24 / с = 100 - 92
24 / с = 8
с = 24 / 8
с = 3
