Question

3•x+50=77......................................100-24:c=92.................................3•c=92-68 решить уравнения

Answer 1

3•x+50=77
3x=77-50
x= 27/3
x=9

100-24:c=92
24/c=100-92
c=24/8
c=3

3•c=92-68
c=24/3
x=8

Answer 2

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

1. 3x + 50 = 77

First, isolate the variable term by subtracting 50 from both sides:

3x = 77 - 50

Now, simplify:

3x = 27

Finally, divide both sides by 3 to find the value of x:

x = 27 / 3

x = 9

So, the solution to the first equation is x = 9.

2. 100 - 24/c = 92

To solve this equation, let's isolate the variable term again. First, subtract 92 from both sides:

100 - 92 = 24/c

Now, simplify:

8 = 24/c

Next, to get rid of the fraction, multiply both sides by c:

8c = 24

Finally, divide both sides by 8 to find the value of c:

c = 24 / 8

c = 3

So, the solution to the second equation is c = 3.

3. 3c = 92 - 68

Subtract 68 from both sides:

3c = 24

Now, divide both sides by 3 to find the value of c:

c = 24 / 3

c = 8

So, the solution to the third equation is c = 8.

To summarize:

1. x = 9
2. c = 3
3. c = 8
