b, - 2(x + 41 ) - (8x - 82 ) = 3 - 9x
c, ( 4x - 1) - (52 + 3x) = 2x - 41
d, - ( 3x + 217 ) - ( 4x - 217) + 5 = 3 - 8x

nhanh nha, mik tick cho, ccau trình bày dễ hiểu, ko cần ''hoặc''
a) 4(x+3)-(2x-12)=x-(-11+4)
b) -(4x-13)+(5x-4)= -3-(-15+7)
c) (5x-3)-(-2x+4)=6x-12
d) (15x+20)-(9x-3)=5x-(-12)
e) (7x+14)+(3x-8)= -(-9x+3)
giúp mình nha.................
