Answer:

0

Step-by-step explanation:

Step 1 - Expand bracket:

[tex]-3(x - 14) + 9x = 6x + 42\\-3(x) + -3(-14) + 9x = 6x + 42\\-3x + 42 + 9x = 6x + 42[/tex]

Step 2 - Combine like terms:

[tex]-3x + 42 + 9x = 6x + 42\\42 + 6x = 6x + 42[/tex]

As both sides are the same, the equation equals 0.

[tex]42 + 6x = 6x + 42\\42 - 42 = 6x + 42 - 4x\\6x = 6x\\6x - 6x = 6x - 6x \\0 = 0\\[/tex]

Hope this helps!
