The value of x is 7.

The value of x is -1/4.

The value of x is 7.

The value of x is 4 1/3.

The value of x is -5.

The value of x is 0.

What is the value of x in the equations?

2(2x + 1) = 30

The first step is to divide both sides of the equation by 2

2x + 1 = 15

Combine similar terms

2x = 15 - 1

2x = 14

x = 7

3(4x - 3) = -12

The first step is to divide both sides of the equation by 3

4X - 3 = -12 /3

4x - 3 = -4

Combine similar terms

4x = -4 + 3

4x = - 1

x = -1/4

4(2x - 7) = 20

The first step is to divide both sides of the equation by 4

2x - 7 = 5

Combine similar terms

2x = 5 + 7

2x = 12

x = 6

7(3x - 4) = 63

The first step is to divide both sides of the equation by 7

3x - 4 = 9

Combine similar terms

3x = 9 + 4

3x = 13

x = 4 1/3

6(3x + 3) = -72

The first step is to divide both sides of the equation by 6

3x + 3 = - 12

Combine similar terms

3x = -12 - 3

3x = -15

x = -5

-2(6x - 3) = 6

The first step is to divide both sides of the equation by -2

6x - 3 = -3

Combine similar terms

6x = -3 + 3

6x = 0

x = 0
