Question

72,9-34(15х+0,3)=52,5

Answer 1

72, 9 - 34 (15 x+0,3) = 52,5
72,9-510X-10,2-52,5=0
10,2 - 510х=0
-510x +10,2=0*(-1)
510x-10,2=0
510x=10,2
X= 0,02

Answer 2

To solve the equation 72.9 - 34(15x + 0.3) = 52.5, follow these steps:

1. Start by distributing the -34 on the left side of the equation: 72.9 - 34(15x) - 34(0.3) = 52.5

2. Multiply -34 by 15x and -34 by 0.3: 72.9 - 510x - 10.2 = 52.5

3. Now, simplify the equation by combining like terms. First, subtract 10.2 from both sides: 72.9 - 10.2 - 510x = 52.5 - 10.2

4. Simplify further: 62.7 - 510x = 42.3

5. To isolate the variable x, subtract 62.7 from both sides: 62.7 - 62.7 - 510x = 42.3 - 62.7

6. Continue simplifying: -510x = -20.4

7. Finally, divide both sides by -510 to solve for x: (-510x) / (-510) = (-20.4) / (-510)

   x = 0.04

So, the solution to the equation is x = 0.04.
