7x - 2x + 3 = 32
7x - 2x +3 -3 = 32 -3
5x + 0 = 29
5x / 5 = 29 / 5
x = 5.8

Subtracting the like term and grouping them together.
7x-2x+3=32
5x+3=32
5x=32-3
5x=29
x=29/5

log base2 (3 - x) + log base2 (a million - 2x) = 5 log base2 (3 - x)(a million - 2x) = 5 log base2 (3 - 7x + 2x^2) = 5 2x^2 - 7x + 3 = 2^5 2x^2 - 7x - 29 = 0 making use of the final formulation, we are able to get x = 5.ninety 4 or x = -2.40 4 (3 sig. fig) wish this facilitates and each and all the terrific! :D

first collect like terms so 7x - 2x = 5x
now 5x + 3 - 3 = 32 - 3 so now its 5x = 29
then 5x/5 = 29/5
so x = 5.8

7x-2x+3=32
Combine similar terms; transpose 3 to the other side of the equation:
5x = 29
Divide both sides of the equation by 5:
x = 29/5 or 5 4/5

1)First you must combine like terms 2)Then subtract 3 from both sides
3)Divide 5 to both sides
x= 29/5 or 5.8
7x-2x+3=32
5x+3=32
-3 -3
-------------------
5x=29
---- ----
5 5
x=29/5 or 5.8
