Answer:
x = 25
Step-by-step explanation:
Both angles are supplementary and will add up to 180°
5x - 5 + 2x + 10 = 180
collect like terms
5x + 2x +10 -5 = 180
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 175/7
x=25

Thanks ^-^
Step-by-step explanation:
From the given statement the unknown number is found to be - 1
The given statements can written in algebraic form as follows;
the unknown number = x
the number is multiplied by 6 = 6x
four less than twice the same number = 2x - 4
then, from the given statement the final equation equation becomes;
6x = 2x - 4
This unknown number can be solved by collecting similar terms together;
6x - 2x = -4
4x = -4
divide through by 4
![\frac{4x}{4} = \frac{-4}{4} \\\\x = -1](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B4%7D%20%3D%20%5Cfrac%7B-4%7D%7B4%7D%20%5C%5C%5C%5Cx%20%3D%20-1)
Thus, the unknown number is - 1

You can write it as:
-4≥x≤6
*The '≥' and '≤' just means that it is greater than or less than but it can still be equal to the number you are comparing it to.
Hope this helps! :)
