To solve this, plug in 8 for X
3+9(8-1) then solve
3+9(7)
3+63
66
I hope I've helped!
Given the equation: (km / 3) - 2x = 4, it is essential to isolate x to obtain the expression to solve it. This is done below:
(km / 3<span>) - 2x = 4
</span>
Adding 2x to both sides:
(km / 3<span>) - 2x + 2x = 4 + 2x
</span>(km / 3<span>) = 4 + 2x
</span>
Subtracting 4 from both sides:
(km / 3<span>) - 4 = 4 + 2x - 4
</span>(km / 3<span>) - 4 = 2x
</span>
Dividing 2 from both sides:
[(km / 3<span>) - 4] /2 = 2x /2
</span>[(km / 3<span>) - 4] /2 = x
</span>x = (km / 6) - 2
The disadvantage would be well, u know how u can divide a even number (not prime unless it's 2) into equal parts by putting the first segment in the middle then the next two in the middle of those? Well, u can't do that with a prime number because u can't divide any prime number like that. It's the best I can explain this concept. I'm pretty sure I'm right, but it's just hard to explain.
