Question

(0,2х+0,4х).3,5=6,3 решить

Answer 1

(0,2х+0,4х)*3,5=6,3
0,6x*3,5=6,3
0,6x=6,3:3,5
0,6x=1,8
x=1,8:0,6
x=3
Ответ: 3

Answer 2

To solve the equation, we first need to simplify the expression on the left-hand side:

(0.2x + 0.4x) * 3.5 = 0.6x * 3.5 = 2.1x

So the equation becomes:

2.1x = 6.3

To solve for x, we can divide both sides by 2.1:

x = 6.3 / 2.1

x = 3

Therefore, the solution to the equation is x = 3.
