Question

0,3x-(2,6-0,9)=1,2+3___________​

Answer 1

Пошаговое объяснение:

0,3х-(2,6-0,9)=1,2+3

0,3х-2,6+0,9=1,2+3

0,3х-1,7=4,2

0,3х=4,2+1,7

0,3х=5,9

х=5,9:0,3

х=19⅔

Answer 2

To solve the equation:

0.3x - (2.6 - 0.9) = 1.2 + 3

First, simplify the equation by performing the operations inside the parentheses and on the right side:

0.3x - (1.7) = 4.2

Now, add 1.7 to both sides of the equation to isolate the term with x:

0.3x - 1.7 + 1.7 = 4.2 + 1.7

0.3x = 5.9

Finally, divide both sides by 0.3 to solve for x:

(0.3x) / 0.3 = 5.9 / 0.3

x = 19.67

So, the solution to the equation is x = 19.67.
