12/11x+120%x=6.512/11x+120%x=6.512/11x+120%x=6.5=(12/11+120%)X=6.5=(1.091+1.2)X=6.5=2.291X=6.5=6.5/2
12/11x+120%x=6.5
12/11x+120%x=6.5
12/11x+120%x=6.5
=(12/11+120%)X=6.5
=(1.091+1.2)X=6.5
=2.291X=6.5
=6.5/2.291=X
x=2.837
12/11x+120%x=6.5
matlab中a=[x(11)/x,x(12)/x;x(21)/x,x(22)/x;x(31)/x,x(32)/x;x(41)/x,x(42)/x;x(51)/x,x(52)/x]咋错了
帮我解四道方程,11/12X-120%X=6.54X+0.4X=70.43X+90%*4=911/12X-120%=6.5
11x+120%x=6.5
11/12x-12%x=6.5
12分之11x—120%x=6.5
12分之11x+120%x=6.5
11/12x-120%x=6.5 这是解方程
11/12X-120%X=6.5解方程
解方程11/12x-百分之120x=6.5
11/12x-x/120%=6.5如何解
解方程 x+4/11x=75 x-1/4x=120 3x+12x=180 8x-x=175
12/11X-120%X=6.5打错了,应该是11/12X-120%X=6.5
x+12x=120
1+x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8 好多年没有用过过数学公式了 想不起来怎么算了 想知道 X值是多少
(x-10)/(x-11)+(x-16)/(x-17)=(x-12)/(x-13)+(x-14)/(x-15)快,急用
x/2x*2-11x-21=x+7/x*2-12x+35
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550必须用解方程
