Question

987-[3030:3-(807-222)+2•x]=362 va rog

Answer 1

Răspuns:

Explicație pas cu pas:

987-[3030:3-(807-222)+2•x]=362

987 - (1010 - 585 + 2*x) = 362

987 - (425 + 2*x) = 362

987 - 425 - 2*x = 362

562 - 2*x = 362

2*x = 562 - 362

2*x = 200

x = 200 : 2 = 100

Answer 2

987 - [ 3030 : 3 - ( 807 - 222 ) + 2 × X ] = 362

987 - ( 1010 - 585 + 2 × X ) = 362

987 - ( 425 + 2 × X ) = 362

425 + 2 × X = 987 - 362

425 + 2 × X = 625

2 × X = 625 - 425

2 × X = 200

X = 200 : 2

X = 100
