Question

133:(38x-95)=7. 15*(53-8x)=75. (6x-29)*8=104

Answer 1

133 : (38х = 95) = 7
38х - 95 = 133 : 7
38х - 95 = 19
38х = 95 + 19
38х = 114
х = 114 : 38
х = 3

Answer 2

To solve these equations, we'll need to isolate the variable 'x' in each of them. Let's go through them one by one:

1. 133:(38x-95) = 7

First, multiply both sides of the equation by (38x-95) to get rid of the denominator:

133 = 7(38x-95)

Now, divide both sides by 7 to isolate (38x-95):

(38x-95) = 133 / 7

(38x-95) = 19

Now, add 95 to both sides to isolate 38x:

38x = 19 + 95

38x = 114

Finally, divide both sides by 38 to solve for x:

x = 114 / 38

x = 3

So, the solution to the first equation is x = 3.

2. 15*(53-8x) = 75

First, simplify the equation by multiplying out the left side:

15*(53-8x) = 75

795 - 120x = 75

Now, subtract 795 from both sides to isolate -120x:

-120x = 75 - 795

-120x = -720

Finally, divide both sides by -120 to solve for x:

x = -720 / -120

x = 6

So, the solution to the second equation is x = 6.

3. (6x-29)*8 = 104

First, simplify the equation by multiplying out the left side:

(6x-29)*8 = 104

48x - 232 = 104

Now, add 232 to both sides to isolate 48x:

48x = 104 + 232

48x = 336

Finally, divide both sides by 48 to solve for x:

x = 336 / 48

x = 7

So, the solution to the third equation is x = 7.

To summarize:

1. x = 3
2. x = 6
3. x = 7
