2. Реши уравнения (20 х Х + 24) : 42 = 2

Question

2. Реши уравнения
(20 х Х + 24) : 42 = 2

Answer 1

20х+24=2*42
20х+24= 84
20х=60
х=3

Answer 2

( 20 × x + 24 ) : 42 = 2
20 × x + 24 = 2 × 42
20 × x + 24 = 84
20 × x = 84 - 24
20 × x = 60
x = 60 : 20
x = 3

Comments

( 20 × x + 24 ) : 42 = 2
20 × x + 24 = 2 × 42
20 × x + 24 = 84
20 × x = 84 - 24
20 × x = 60
x = 60 : 20
x = 3
