Question

0,8-(15х-9,7х)=127,2​

Answer 1

-15x+9,7x=127,2-0,8
-5,3x=126,4
X= -126,4/5,3=-1264/53. Хз странно. Дальше не делится

Answer 2

To solve the equation 0.8 - (15x - 9.7x) = 127.2, follow these steps:

Step 1: Simplify the equation Combine like terms on the left-hand side: 0.8 - (15x - 9.7x) = 0.8 - 5.3x

Step 2: Set up the equation Now the equation becomes: 0.8 - 5.3x = 127.2

Step 3: Isolate the variable To isolate the variable (x) on one side of the equation, we need to get rid of the constant term (0.8) on the left-hand side. We can do this by subtracting 0.8 from both sides of the equation:

0.8 - 5.3x - 0.8 = 127.2 - 0.8

This simplifies to: -5.3x = 126.4

Step 4: Solve for x Now, to find the value of x, divide both sides by -5.3:

x = 126.4 / -5.3

x ≈ -23.79

So, the solution to the equation is approximately x = -23.79.
