1.4x×0.9=x+52
1.4x×0.9=x+52
4x×0.9=x+52
3.6x=x+52
3.6x-x=52
2.6x=52
x=52÷2.6
x=20
不懂可追问,有帮助请采纳,谢谢!
1.4x×0.9=x+52
1.26x=x+52
1.26x-x=52
0.26x=52
x=52÷0.26
x=200
有帮助请采纳,谢谢!
1.26X=X+52
0.26X=52X=200
1.4x×0.9=x+52
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
9x-0.9乘7=2x+2.1 x=?9x-0.9乘7=2x+2.1 x=?还有:3(2x-1.2)=2(x+3.5) x=?2.4x-9.8=1.4x-9
(X+X)+(X-X)+(X*X)+(X/X)=100
1.4x-x=9.8求x
x+(x-1.4)+1.5x=33.
3x-x=0.9求x
x-2=(104-x)+2 6x-59=10x-75 (x+10)+(x-15)=280-x4(x-62)=x-38 60x-40=(60+20)*(x-5) 32x+32*0.5-25x+64x=24x+496-49x x+15=3*(109-x ) 5(3x-1.4)=2(6x-0.5) 3(x+0.9)=5(x-1.7) 13x-4(2x+5)=17(x-2)-4(2x-1) (13x+8)/3=5x-1x-60=2[(3561-x)+100]+1 (x+9)+12=2[(x-9)-1
52-X=4+X+X
解方程:(x+10)+(x-15)=280-x x+15=3*(109-x) 5(3x-1.4)=2(6x-0.5) 3(x+0.9)=5(x-1.7) 13x-4(...解方程:(x+10)+(x-15)=280-xx+15=3*(109-x) 5(3x-1.4)=2(6x-0.5) 3(x+0.9)=5(x-1.7)13x-4(2x+5)=17(x-2)-4(2x-1)
