You can only add x terms together only if they have the same exponent. For example you can add 2x^2 and x^2 but you cannot add x^2 and x^3.
In this particular problem, you can add 4x^4 and x^4, and x and 8x. So,
<span>
(x + 4x^4) + (x^4 - 2 + 8x)
</span>= 5x^4 + 9x -2
Answer:
x = 6
Step-by-step explanation:
10x-5 = 7x+13 1. -7 on both sides
3x-5 = 13 2. +5 on both sides
3x = 18 3. /3 on both sides
x = 6
The answer would be 1 million
