Question

(x - 5,7)* 0,3 = 4,02

Answer 1

(х-5,7)*0,3=4,02
х-5,7=4,02:0,3
х-5,7=13,4
х=13,4+5,7
х=19,1

(19,1-5,7)*0,3=4,02
1)19,1-5,7=13,4
2)13,4*0,3=4,02

Answer 2

I assume that the equation is:

0.3(x - 5.7) = 4.02

To solve for x, we can start by simplifying the left-hand side of the equation by distributing the 0.3:

0.3x - 1.71 = 4.02

Next, we can add 1.71 to both sides of the equation to isolate the x term on one side:

0.3x = 5.73

Finally, we can divide both sides of the equation by 0.3 to solve for x:

x = 19.1

Therefore, the solution to the equation is x = 19.1.
