Question

18-x : 1,5=3,4 и еще один 216: x - 9,3 = 50,7

Answer 1

х:1,5=18-3,4
х:1,5=14,6
х=14,6*1,5
х=21,9

216:х=50,7+9,3
216:х=60
х=216:60
х=3,6

Answer 2

To solve the equations, let's take them one by one:

1. Equation 1: 18 - x / 1.5 = 3.4

To isolate x, we need to undo the operations in reverse order. The first step is to multiply both sides of the equation by 1.5 to get rid of the division:

1.5 * (18 - x) = 3.4

Now, distribute the 1.5:

27 - 1.5x = 3.4

Next, subtract 27 from both sides to isolate the term with x:

-1.5x = 3.4 - 27

Combine the numbers on the right side:

-1.5x = -23.6

Finally, divide both sides by -1.5 to solve for x:

x = -23.6 / -1.5

x = 15.73333333... (approximately)

So, the value of x in the first equation is approximately 15.73.

2. Equation 2: 216 / x - 9.3 = 50.7

First, add 9.3 to both sides to isolate the fraction:

216 / x = 50.7 + 9.3

Combine the numbers on the right side:

216 / x = 60

Now, to solve for x, we can cross-multiply:

216 = 60x

Finally, divide both sides by 60 to get the value of x:

x = 216 / 60

x = 3.6

So, the value of x in the second equation is 3.6.

In summary:

• The value of x in the first equation is approximately 15.73.
• The value of x in the second equation is 3.6.
