" -1/2(-3/2x + 6x + 1) −<span> 3x " ;
= (-1/2 * -3/2 x) + (-1/2 * 6x) + (-1/2 * 1) </span>− <span>3x ;
= [ (-1 *-3) /(2*2)] x + (-3x) + (-1/2) ] </span>− <span>3x ;
= [ (3/4)x </span>− 3x − (1/2) ] −<span> 3x ;
= </span>(3/4)x − 3x − (1/2) − 3x ;
= ?? ; → Combine the "like terms" ;
→ "(3/4)x − 3x − 3x " = ?? ;
→ "(3/4)x − 3x = "(-9/4)x";
→ "(-9/4)x − 3x = "(-21/4)x " = " (-5)x " ;
→ The answer is: " (-5)x − " ;
