一、解方程:
(1)6x=3x-12 (2)2y― = y―3
(3)-2x=-3x+8 (4)56=3x+32-2x
(5)3x―7+6x=4x―8 (6)7.9x+1.58+x=7.9x-8.42
(7)3(2x+5)=2(4x+3)-3 (8)4y﹣3(20﹣y)=6y﹣7(9﹣y)
(9)7(2x-1)-3(4x-1)=4(3x+2)-1 (10)(5y+1)+ (1-y)= (9y+1)+ (1-3y)
(11) 2(x-2)+2=x+1 (12) 2(x-2)-3(4x-1)=9(1-x)
(13) 11x+64-2x=100-9x (14) 15-(8-5x)=7x+(4-3x)
(15) 3(x-7)-2[9-4(2-x)]=22 (16) 12x-10.3x=15
(17) 20.52x-(1-0.52)x=80 (18) 43x+7=32-2x
(19) 53x+5(138-x)=540 (20) 63x-7(x-1)=3-2(x+3)
