Question

2)9,7·х+15,32=24,05 3)(х-7,5) ·28,7=100,45

Answer 1

2)9,7x=24,05-15,32
9,7x=8,73
x=8,73:9,7
x=0,9
3)x•28,7-7,5•28,7=100,45
28,7x-215,25=100,45
28,7x=100,45+215,25
28,7x=315,7
x=315,7:28,7
x=11

Answer 2

2)9,7x=24,05-15,32
9,7x=8,73
X=0,9
3)28,7x-215,25=100,45
28,7x=315,7
X=11

Answer 3

To solve these equations for the variable "x," you can follow these steps:

1. Solve for x in the equation 9.7x + 15.32 = 24.05:

First, subtract 15.32 from both sides of the equation:

9.7x + 15.32 - 15.32 = 24.05 - 15.32

9.7x = 8.73

Now, divide both sides by 9.7 to isolate x:

9.7x / 9.7 = 8.73 / 9.7

x ≈ 0.899

So, the solution to the first equation is approximately x ≈ 0.899.

2. Solve for x in the equation (x - 7.5) * 28.7 = 100.45:

First, divide both sides of the equation by 28.7 to isolate (x - 7.5):

(x - 7.5) * 28.7 / 28.7 = 100.45 / 28.7

x - 7.5 = 3.5

Now, add 7.5 to both sides to solve for x:

x - 7.5 + 7.5 = 3.5 + 7.5

x ≈ 11

So, the solution to the second equation is approximately x ≈ 11.
