Question

Уравнения (y+50):14=4 120:(x-19)=6 77-(28+y)=27

Answer 1

1) y+50=4*14

y+50=56

y=6

2) 120:6= x-19

20=x-19

x= 39

3) 77-28-y=27

77-28-27=y

y= 22

Answer 2

Ответ:

1) у = 6  2) х = 39  3) у = 22

Пошаговое объяснение:

1-ое уравнение:

( у + 50 ) : 14 = 4

у + 50 = 14 * 4

у + 50 = 56

у = 56 - 50

у = 6

Проверка:

( 6 + 50 ) : 14 = 4

         56 : 14 = 4

                  4 = 4

2-ое уравнение:

120 : ( х - 19 ) = 6

х - 19 = 120 : 6

х - 19 = 20

х = 19 + 20

х = 39

Проверка:

120 : ( 39 - 19 ) = 6

         120 : 20 = 6

                    6 = 6

3-е уравнение:

77 - ( 28 + у ) = 27

28 + у = 77 - 27

28 + у = 50

у = 50 - 28

у = 22

Проверка:

77 - ( 28 + 22 ) = 27

           77 - 50 = 27

                   27 = 27

Answer 3

To solve each of these equations, we'll follow the steps to isolate the variable (y or x) on one side of the equation.

1. (y + 50) / 14 = 4

To solve for y: Step 1: Multiply both sides by 14 to get rid of the fraction. (y + 50) = 4 * 14

Step 2: Simplify the right side of the equation. (y + 50) = 56

Step 3: Now, isolate y by subtracting 50 from both sides. y = 56 - 50

y = 6

So, the value of y is 6.

2. 120 / (x - 19) = 6

To solve for x: Step 1: Multiply both sides by (x - 19) to get rid of the fraction. 120 = 6 * (x - 19)

Step 2: Simplify the right side of the equation. 120 = 6x - 114

Step 3: Now, isolate x by adding 114 to both sides. 6x = 120 + 114

6x = 234

Step 4: Finally, divide both sides by 6 to find the value of x. x = 234 / 6

x = 39

So, the value of x is 39.

3. 77 - (28 + y) = 27

To solve for y: Step 1: Simplify the left side of the equation by performing the operation within the parentheses. 77 - (28 + y) = 77 - 28 - y

Step 2: Continue simplifying. 49 - y = 27

Step 3: Now, isolate y by subtracting 49 from both sides. -y = 27 - 49

-y = -22

Step 4: To solve for y, multiply both sides by -1 (to get rid of the negative sign in front of y). y = 22

So, the value of y is 22.

Therefore, the solutions for the equations are: y = 6 x = 39 y = 22
