X=8+y
x+y=70

Rewrite the first equation to x-y=8
Copy the second equation   x+y=70

Add the two equations and you get 2x=78
Therefore, x=39. Since this is the bigger number the smaller number(y) would have to be 31 because you subtract 8 from x which is 39. 39 is your answer.

50 POINTS, I NEED IT QUICK PLSS

The thing that's wrong with the equation is that 2 shouldn't be multiplied by 4 but should have been added.

<h3>How to illustrate the information?</h3>

From the information given, it can be seen that the equation is:

(3x²)(-2x⁴) = 3(-2)x² × x⁴ = 6x^8

Based on the information above, this calculation is incorrect. The correct calculation will be:

(3x²)(-2x⁴) = 3(-2)x² × x⁴

= -6x^6

Therefore, the multiplication should be an addition of the power.
