I assume you mean 3x-2=5
To solve this (to find x) you need to make it so that on 1 side you have ?x and the other, an equation.
To make 3x-2 equal 3x, you need to add 2, once you have done that, that side equals 2 more than the other side so you need to add 2 to 5.
The equation is now 3x-2+2=5+2
OR 3x=7
Divide 7 by 3 to get x.
7/3=2.33333..... (the 3 reccures)
Hope this helps :)
(x^2-2) (x^2+3x+5)= x^2(x^2+3x+5) -2(x^2+3x+5)= x^4 +3x^3 +5x^2 -2x^2 -6x -10= x^4 +3x^3 +3x^2 -6x -10
-(3x -2) = 17 -3x + 2 = 17 - 3x = 15 x = -5
If you meant (x/5) + 2 = 3x/5 = 1x =5-----------------If you meant x/(5+2) = 3x/(7) = 3x = 21
The difference between a one step problem, and a two step problem is very simple. It refers to the amount of effort and steps that are in your problem. For example, 3x=5, is a one step equation. 3x-7=5, is a two step equation.
Assuming you mean 3x - 2 = 9x - 5...3x - 2 = 9x - 53x + 3 = 9x3 = 6x0.5 = x
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
Here is how you solve this problem... 5x*4-3x*5*2x-9= (Combine like-terms) 5x-3x*2x= 2x*2x=(2x)2 (Add the rest of the problem) (2x)2*4*5-9=(2x)2*20-9 (2x)2*11 (2x)2 *11= your answer
3x+5=2, 3x=2-5 (sign changes) 3x=-3 x=-1
(x^2-2) (x^2+3x+5)= x^2(x^2+3x+5) -2(x^2+3x+5)= x^4 +3x^3 +5x^2 -2x^2 -6x -10= x^4 +3x^3 +3x^2 -6x -10
eq: 3x+5=7 =3x=7-5 =3x=2 =x=2/3
(3x+2)-(5+7x) = 3x+2-5-7x = -4x-3 3x+2 is -4x-3 times greater than 5+7x.
You're asking for the difference: (3x + 2) - (5 - 7x).(3x + 2) - (5 - 7x) =3x + 2 - 5 + 7x =10x - 3.It is (10x - 3) greater.
-(3x -2) = 17 -3x + 2 = 17 - 3x = 15 x = -5

If the question is x + 4z - 5 - 3x when x = 2 and z = 3x, then First simplify the original statement x + 4z - 5 - 3x = 4z - 5 - 2x Secondly substitute in 3x for z 4z - 5 - 2x = 4*3x - 5 - 2x = 12x - 5 - 2x = 10x - 5 Lastly substitute 2 for the x 10x - 5 = 10*2 - 5 = 20 - 5 = 15 or x + 4z - 5 - 3x when x = 2 and z = 3x, so z = 3*2 = 6 x + 4z - 5 - 3x = 4z - 5 - 2x (replace the variables with the corresponding values) = 4*6 - 5 - 2*2 = 24 - 5 - 4 = 24 - 9 = 15
The factors are [3x + 5 - 2*sqrt(10)] and [3x 5 + 2*sqrt(10)].
3x - 2 + 5 = 16 3x + 3 = 16 3x = 13 x = 13/3 ~ 4.333
