Question

If x + 2x + 3x + 4 = x + x - 8 what is the value of x​

Answer 1

-3

Explanation:

x+2x+3x=6x

6x+4=x+x-8

6x+4=2x-8

(bring like terms together)

6x-2x=-8-4

4x=-12

x=-12/4

x=-3

Answer 2

`\huge\boxed{\sf x = -3}`

Explanation:

Given equation:

x + 2x + 3x + 4 = x + x - 8

• Combine like terms

6x + 4 = 2x - 8

• Subtract 2x from both sides

6x - 2x + 4 = -8

4x + 4 = -8

• Subtract 4 from both sides

4x = -8 - 4

4x = -12

• Divide both sides by 4

x = -12/4

x = -3
