How to solve the following equation? 1.8-3x = 0.315 + 2x = 34 / 2


1.8-3x=0.3
3x=1.8-0.3
3x=1.5
x=0.5
15+2x=34/2
30+4x=34
4x=4
x=1

How to solve the equation of 0.03-3x / 0.03-6.5 = 3 (5-2x) / 0.05-5.5?
Are you sure it's right?


*It's 10
0.3-30x/0.03-65=30(5-2x)/0.05-55
0.3-1000x-65=600(5-2x)-55
200x=3009.7
x=15.0485



In equilateral triangle ABC, point E is on line AB, point D is on line BC, and ED = EC. If the side length of triangle ABC is 1, AE = 2, then the length of CD is______ .


When e is on the extension line of segment Ba and D is on the extension line of segment BC, as shown in Figure 1, if EF ⊥ BD is made through E and the foot is f point, then ∠ EFB = 90 °, ∵ EC = ed, ∵ f is the midpoint of CD, that is, CF = DF = 12CD, ∵ △ ABC is an equilateral triangle, ∵ ABC = 60 °, ∵ bef = 30 °, ∵ be = AB + AE = 1 + 2 = 3, ∵ FB = 12eb = 32, ∵ CF = fb-bc = 12, then CD = 2cf = 1; when e is on the extension line of segment ab When D is on the extension line of line segment CB, as shown in Figure 2, if EF ⊥ BD is made through E and the foot is f point, then ∠ EFC = 90 °, ∵ EC = ed, ∵ f is the middle point of CD, that is, CF = DF = 12CD, ∵△ ABC is equilateral triangle,
