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!
