Question

4x=28 3x-6=16 5x-7=33-x

Answer 1

Ответ:

4x= 28

x = 7

3x - 6 = 16

3x = 16 +6

3x = 22

x = 7,3

5x - 7 = 33 - x

5x + x = 33 +7

6x = 40

x = 6,6

Answer 2

4х=28

х=28:4

х=7

3х-6=16

3х=16+6

3х=22

х=22/3=7 1/3

5х-7=33-х

5х+х=33+7

6х=40

х=40/6=20/3=6 2/3

Answer 3

To solve these equations, we'll go through them one by one:

1. 4x = 28

To solve for x, we divide both sides of the equation by 4:

4x/4 = 28/4

x = 7

So the solution for this equation is x = 7.

2. 3x - 6 = 16

To isolate x, we first add 6 to both sides of the equation:

3x - 6 + 6 = 16 + 6

3x = 22

Next, we divide both sides of the equation by 3:

(3x)/3 = 22/3

x = 22/3

So the solution for this equation is x = 22/3.

3. 5x - 7 = 33 - x

To solve for x, we first simplify the equation by combining like terms:

5x + x = 33 + 7

6x = 40

Next, we divide both sides of the equation by 6:

(6x)/6 = 40/6

x = 20/3

So the solution for this equation is x = 20/3.

To summarize, the solutions for the given equations are:

1. x = 7
2. x = 22/3
3. x = 20/3
