Answer:

x = -10

Explanation:

x+x+2+x+4+x+6=-28​

Combine all like terms

4x + 2 + 4 + 6 = -28

4x + 12 = -28

Simplify by subtracting 12 on both sides.

4x = -40

Divide by 4.

x = -10

Check

x+x+2+x+4+x+6=-28

(-10) + (-10) + 2 + (-10) + 4 + (-10) + 6 = -28

-28 = -28

Answer:

X=4

Explanation:

Simplifying

x + x + 2 + x + 4 + x + 6 = 28

Reorder the terms:

2 + 4 + 6 + x + x + x + x = 28

Combine like terms: 2 + 4 = 6

6 + 6 + x + x + x + x = 28

Combine like terms: 6 + 6 = 12

12 + x + x + x + x = 28

Combine like terms: x + x = 2x

12 + 2x + x + x = 28

Combine like terms: 2x + x = 3x

12 + 3x + x = 28

Combine like terms: 3x + x = 4x

12 + 4x = 28

Solving

12 + 4x = 28

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12' to each side of the equation.

12 + -12 + 4x = 28 + -12

Combine like terms: 12 + -12 = 0

0 + 4x = 28 + -12

4x = 28 + -12

Combine like terms: 28 + -12 = 16

4x = 16

Divide each side by '4'.

x = 4

Simplifying

x = 4
