(54-x)*3.1=12.4*2(54-x)*3.1=12.4*2(54-x)*3.1=12.4*254-x=12.4*2/3.154-x=4*2x=54-8x=46(54-x)×3.1=12.4×
(54 - x) * 3.1 = 12.4 * 2
(54 - x) * 3.1 = 12.4 * 2
(54 - x) * 3.1 = 12.4 * 2
54-x=12.4*2/3.1
54-x=4*2
x=54-8
x=46
(54 - x) ×3.1 = 12.4×2
两边同除以3.1:54-x=4×2
54-x=8
因为减数=被减数-差
所以, x=54-8
x=46.
x+25%x=54-x急
1.5x+x=12.
5X-X=54
x+x+x+y+y=54 x+x+x+y=46
1.(1/X-1 )-2=X^-3X/X^-12.(X/X+1)^+5(X/X+1)+6=03.(8(X^+2X)/X^-1)+ 3(X^-1)/X^+2x
X+X+X+Y+Y=54 X=( ) Y+Y+Y+X+X=56 X=( )
(X+X)+(X-X)+(X*X)+(X/X)=100
