Question

1) (63-5x):3=6: 2) 133:(38x-95)=7

Answer 1

1) (63-5х):3=6
     63-5х=6*3
     63-5х=18
     -5х=18-63
     -5х=-45
     х=-45:(-5)
     х=9
2) 133:(38x-95)=7
     38x-95=133:7
     38x-95=19
     38x=19+95
     38x=114
     x=114:38
     x=3  

Answer 2

1) (63-5х):3=6
63-5х=6*3
63-5х=18
5х=63-18
5х=45
х=45:5
х=9
Проверка
(63-5*9):3=6
1)5*9=45
2)63-45=18
3)18:3=6

2)133:(38х-95)=7
38х-95=133:7
38х-95=19
38х=19+95
38х=114
х=114:38
х=3
Проверка
133:(38*3-95)=7
1)38*3=114
2)114-95=19
3)133:19=7

Answer 3

To solve these equations, we'll first simplify and isolate the variable x in each equation.

1. (63-5x)/3 = 6

To isolate x, you can multiply both sides of the equation by 3 to get rid of the fraction:

(63-5x) = 6 * 3

63 - 5x = 18

Now, you can isolate x by moving the constant terms to the other side of the equation:

-5x = 18 - 63

-5x = -45

To solve for x, divide both sides by -5:

x = -45 / -5

x = 9

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

2. 133 / (38x - 95) = 7

To isolate x in this equation, first, multiply both sides by (38x - 95) to get rid of the fraction:

133 = 7(38x - 95)

Now, distribute 7 on the right side:

133 = 266x - 665

Next, move the constant terms to the other side of the equation:

266x = 133 + 665

266x = 798

To solve for x, divide both sides by 266:

x = 798 / 266

x = 3

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