Answer 1

Resposta:

Explicação passo-a-passo:

encontre as raizes  

f)

2x +327=-x-963    isoalr O (X)) atenção no SINAL

2x + 327 + x = 963

2x + x = 963 - 327

3x =  636

x = 636/3

x = 212

g)

9X-3947=7X+235

9x - 3947 - 7x = 235

9x - 7x = 235 + 3947

2x = 4182

x = 4182/2

x = 2091

H)

4X+328=689

4x = 689 - 328

4x = 361

x = 361/4

I)

2 x+93=245

2x = 245 - 93

2x = 152

x = 152/2

x = 76

j)

5x-690=9535

5x = 9535 + 690

5x = 10.225

x = 10.225/5

x = 2.045
