Answer:
x = 6
Step-by-step explanation:
First, we need to cross multiply on both sides, which gives us:
9 * (5x - 6) = 27 * (2 + x)
45x - 54 = 54 + 27x
Now, we want to isolate x on either side.
We can substract 54 from both sides:
(45x - 54 = 54 + 27x) - 54
45x - 108 = 27x
We then subtract 45 from both sides:
(45x - 108 = 27x) - 45
-108 = -18x
Finally, we divide both sides by -18:
(-108 = -18x) / -18
6 = x
Answer:
42x^2 - 7x - 6x + 1
42x^2 - 13x + 1 for FOIL method
To solve for x
7x - 1 = 0
7x = 1
x = 1/7
6x - 1 = 0
6x = 1
x = 1/6
