TienesUnError A)
$4(3x+4)+5(2x+3)=7(3x-4) \\ 12x+16+10x+15=21x-28 \\ 22x+31=21x-28 \\ 22x-21x=-31-28 \\x=-59$

b)
$9(x+3)+2(4-x)=6(x+1)+7 \\ 9x+27+8-2x=6x+6+7 \\ 7x+35=6x+13 \\7x-6x=13-35 \\x=-22$

c)
$3(x-1)+2(3x+4)=2x-3 \\ 3x-3+6x+8=2x-3 \\9x+5=2x-3 \\9x-2x=-3-5 \\ 7x=-8 \\ x=- \frac{8}{7}$

d)
$2x+3(5x-2)-(9x+1)=6(x+3)-(1-x) \\ 2x+15x-6-9x-1=6x+18-1+x \\ 8x-7=7x+17 \\8x-7x=17+7 \\x=24$
