Question

determinati in fiecare caz numarul natural necunoscut x din egalitatile

2456-x=1237
x+125=2003
x-2359-2359=17206
x-130-157=3156
7378+×12002

plzzzzz ajutor repede dau coroana​

Answer 1

Răspuns:

2456-x=1237

x=2456-1237=>x=1219

x+125=2003

x=2003-125=>x=1878

x-2359-2359=17206

x=17206+2359+2359=>x=21924

x-130-157=3156

x=3156+130+157=>x=3443

7378+×=12002

x=12002-7378=>x=4624

Answer 2

Răspuns:

Explicație pas cu pas:

2456-x=1237

x = 2456 - 1237

x = 1219

x+125=2003

x = 2003 - 125

x= 1878

x-2359-2359=17206

x - 2359 = 17206 + 2359

x - 2359 = 19565

x= 19565 + 2359

x = 21924

x-130-157=3156

x - 130 = 3156 + 157

x - 130 = 3313

x = 3313 + 130

x = 3443

7378+x = 12002

x = 12002 - 7378

x= 4624
