Question

1725+275-[2x(a-9x8-627)]+(834-900:3+6x7)x2=1614

Answer 1

Răspuns:

a= 1468

Explicație pas cu pas:

1725+275-[2×(a-9×8-627)]+(834-900:3+6×7)×2=1614

1725+275-[2×(a-72-627)]+(834-300+42)×2=1614

1725+275-[2×(a-699)]+576×2=1614

1725+275-(2a-1398)+1152=1614

1725+275-2a+1398+1152=1614

4550-2a=1614

-2a=1614-4550

-2a=2936

2a=2936

a=2936:2

a=1468

Answer 2

Răspuns:

a = 1468

Explicație pas cu pas:

1725+275-[2x(a-72-627)]+(834-300+42)x2= 1614

1725+275-[2x(a-699)]+ 576 x 2 = 1614

1725+ 275 - (2a- 1398) + 1152 = 1614

1725 + 275 - 2a + 1398 + 1152 = 1614

4450 - 2a = 1614

-2a = 1614 - 4550

a = -2936/-2

a = 1468
