B) X - 6 . (X + 5) = -6 . (X + 5) -3

C) 2 - 5 . (X + 2) = 14 - X

D) 4X = 3 - (X + 5)

E) 5 - (T + 1) = 7 + 2T

F) 2 - 3 . (Y + 2) = 7 - (Y - 2)



Me ajudem por favor!!!!

Answer 1

$A) \\ 3-(x-4)=14+2x \\ \\ 3-x+4=14+2x \\ \\ -x-2x=14-3-4 \\ \\ -3x=7 \\ \\ x=- \frac{7}{3}$

$B) \\ x-6.(x+5)=-6.(x+5)-3 \\ \\ x-6x-30=-6x-30-3 \\ \\ x-6x+6x=-30-3+30 \\ \\ x=-3$

$C) \\ 2-5(x+2)=14-x \\ \\ 2-5x-10=14-x \\ \\ -5x+x=14+10-2 \\ \\ -4x=22 \\ \\ x=- \frac{22}{4} = -\frac{11}{2}$

$D) \\ 4x=3-(x+5) \\ \\ 4x=3-x-5 \\ \\ 4x+x=3-5 \\ \\ 5x=-2 \\ \\ x=- \frac{2}{5}$

$E) \\ 5-(T+1)=7+2T \\ \\ 5-T-1=7+2T \\ \\ -T-2T=7-5+1 \\ \\ -3T=3 \\ \\ T=-1$

$F) \\ 2-3(y+2)=7-(y-2) \\ \\ 2-3y-6=7-y+2 \\ \\ -3y+y=7+2-2+6 \\ \\ -2y=13 \\ \\ y=- \frac{13}{2}$
