4x+3×0.7=6.5
4x+3×0.7=6.5
4x+3×0.7=6.5
4x+3*0.7=6.54x+2.1=6.54x=6.5-2.14x=4.4x=4.4/4x=1.1

解:4x+2.1=6.5
4x=6.5-2.1
x=4.4÷4
x=1.1
1.1
1.1
6.5÷0.7÷3÷4=x
4x=4.4
x=1.1
4.4
4x=6.5-3×0.7
希望帮到你
4x加2.1等于6.5 6.5减2.1等于4.4在除以4等于1.1所以x等于1.1
4x=6.5-3×0.7
4x=4.4
x=4.4/4
x=1.1
计算0.5x-0.7=6.5-1.3x 2(x-2)-3(4x-1)=9(1-x)
4x+3×0.7=6.5
4X+3×0.7=6.5
请问,这几道关于一元一次方程的题目,我做对了没有?(1) 3X+0.5X=10.53.5x=10.5X=3(2) 5X-2X=93x=9X=3(3) X+6x+5x=1812x=18X=1.5(4) 10x-4.5X=2.5乘以3.55.5x=8.75X=1.59(5) -6.5X=2.5乘以3.5-6.5x=8.75X=-1.34

解方程:4(x+0.3)=4.8 3*0.7+4x=6.5 5.5x-1.3x=12.6
4x+3*0.7=6.5 95%x-2/5x=55 4x-1.6=36 4x+3*0.7=6.595%x-2/5x=554x-1.6=36
1/3=5/12x-x/4 2/3-8x=3-1/2x 0.5x-0.7=6.5-1.3x 1/6(3x-6)=2/5x-3
-(X²+3X)+2(4X+X²)其中X=-2
解4道方程(要步骤,十二分之5x-四分之x=三分之1 三分之2-8x=3-二分之1x 0.5x-0.7=6.5-1.3x 六分之1(3x-6)=五分之二x-3
3x-2=4+x,求x=多少?
(3x+2)(x+3)=x+4
4x-8=3x+24 x是多少
5x-2=3x+4 x等于什么?
4x(5x-2)=3(5x-2)
3x-7+4x=6x-2
4x(2x-1)=3(2x-1)
120%x-十二分之十一x=6.5 4x+0.4x=70.4 3x+90%×4=9 这几个方程怎么解
