Question

0,72x + 0,065x-0,0014=0,03​

Answer 1

Ответ:

$0.72x+0.065x=0.03+0.0014\\0.785x=0.0314$

$x=\frac{0.0314}{0.785} \\x= 0.04$

Answer 2

0.72х+0.065x-0.0014=0.03 | * 10000

7200x+650x-14=300

7850x=314 | : 7850

x=0.04

Answer 3

To solve the equation 0.72x + 0.065x - 0.0014 = 0.03, we can combine like terms on the left side of the equation:

(0.72x + 0.065x) - 0.0014 = 0.03

0.785x - 0.0014 = 0.03

Next, we can isolate the variable x by adding 0.0014 to both sides of the equation:

0.785x = 0.03 + 0.0014

0.785x = 0.0314

To solve for x, divide both sides of the equation by 0.785:

x = 0.0314 / 0.785

x ≈ 0.04

Therefore, the solution to the equation is x ≈ 0.04.
