Question

va rog ajutatima la aceste 2 exercitii. x•4:10+101=133,. (x+282-75):2=104

Answer 1

x × 4 : 10 + 101 = 133

x × 4 : 10 = 133 - 101

x × 4 : 10 = 32

x × 4 = 32 × 10

x × 4 = 320

x = 320 : 4

x = 80

( x + 282 - 75 ) : 2 = 104

( x + 207 ) : 2 = 104

( x + 207 ) = 104 × 4

x + 207 = 208

x = 208 - 207

x = 1
