Question

(6,39 : х – 7,5) * 2,5 = 34,5

Answer 1

6,39 : х – 7,5=34,5:2,5
6,39 : х=13,8+7,5
х=6,39:21,3
х=0,3

Answer 2

To solve the equation, let's first simplify the expression on the left side of the equation:

(6.39 * x - 7.5) * 2.5 = 34.5

Now, we'll distribute the 2.5 to the terms inside the parentheses:

(2.5 * 6.39 * x) - (2.5 * 7.5) = 34.5

Now, perform the calculations:

15.975 * x - 18.75 = 34.5

Next, isolate the term with "x" on one side of the equation:

15.975 * x = 34.5 + 18.75 15.975 * x = 53.25

Finally, solve for "x" by dividing both sides by 15.975:

x = 53.25 / 15.975 x ≈ 3.33

So, the value of "x" that satisfies the equation is approximately 3.33.
