1.(x-3)÷2=7.5 2.3x+x=30 3.15x+x=40 4.2.5x-6=18.5 5.3x+7=59.2
(1)x与2的和是6与3.15的积,求x(2)x的8倍减去3个x,差是12,求x
9x除以2=3.15*2
4x x=3.15怎么解
谁能帮下我把下面30道一元一次方程解了1.2(x-2)-3(4x-1)=9(1-x) 2.11x+64-2x=100-9x 3.15-(8-5x)=7x+(4-3x) 4.3(x-7)-2[9-4(2-x)]=22 5.3/2[2/3(1/4x-1)-2]-x=2 6.2(x-2)+2=x+1 7.0.4(x-0.2)+1.5=0.7x-0.38 8.30x-10(10-x)=100 9.4(x+2)=5(x-2) 10.120
1.2(x-2)-3(4x-1)=9(1-x) 2.11x+64-2x=100-9x 3.15-(8-5x)=7x+(4-3x) 4.3(x-7)-2[9-4(2-x)]=22 5.3
