Question

125+{14x[40+(a+240):4]-34}x14=38849

Answer 1

Răspuns:

Explicație pas cu pas:

125 + { 14 × [ 40 + ( a + 240 ) : 4 ] - 34 } × 14 = 38 849

{ 14 × [ 40 + ( a + 240 ) : 4 ] - 34 } × 14 = 38 849 - 125

{ 14 × [ 40 + ( a + 240 ) : 4 ] - 34 } × 14 = 38 724

14 × [ 40 + ( a + 240 ) : 4 ] - 34 = 38 724 : 14

14 × [ 40 + ( a + 240 ) : 4 ] - 34 = 2 766

14 × [ 40 + ( a + 240 ) : 4 ] = 2 766 + 34

14 × [ 40 + ( a + 240 ) : 4 ] = 2 800

40 + ( a + 240 ) : 4 = 2 800 : 14

40 + ( a + 240 ) : 4 = 200

( a + 240 ) : 4 = 200 - 40

( a + 240 ) : 4 = 160

a + 240 = 160 × 4

a + 240 = 640

a = 640 - 240

a = 400
