1. Simplifying
4 + 6.5x = 36.5

Solving
4 + 6.5x = 36.5

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4' to each side of the equation.
4 + -4 + 6.5x = 36.5 + -4

Combine like terms: 4 + -4 = 0
0 + 6.5x = 36.5 + -4
6.5x = 36.5 + -4

Combine like terms: 36.5 + -4 = 32.5
6.5x = 32.5

Divide each side by '6.5'.
x = 5

Simplifying
x = 5


2. x in (-oo:+oo)

12-((3/5)*x) = 39 // - 39

12-((3/5)*x)-39 = 0

(-3/5)*x-39+12 = 0

-3/5*x-27 = 0 // + 27

-3/5*x = 27 // : -3/5

x = 27/(-3/5)

x = -45

x = -45

X/2 -5=20 please give details
vladimir1956 [14]

Answer: x=50

how?

\frac{x}{2} - 5= 20 (first ADD 5 with 20 whatever you do on one side you have to do it to the other) so that gives us:

\frac{x}{2}=25 (we see that 2 is being divided by x and we want X alone so the inverse of division is MULTIPLICATION)

25 x 2= 50

therefor the x=50
