3.5x-0.5x=2 .

3.5x-0.5x=2
3x=2
X = 2 / 3

5x-1=(5x-2)^0
solve equations

5x-1=(5x-2)^0
5X-1=1
5x=2
x=2/5

If (x + a) x (x + 2) = the square of x-5x-14

（x+a）(x+2)
=x²+(a+2)x+2a
So a + 2 = - 5
a=-7

X squared - 5x = - 2

Solution:
x^2-5x=-2
x^2-5x+(5/2)^2-(5/2)^2=-2
(x-5/2)^2=25/4-8/4=17/4
X-5 / 2 = ± root 17 / 2
X = 5 / 2 ± root 17 / 2

3x = 45, solved by equation

3x=45
x=45÷3
x=15

Solution of equation 24-3x = 6

24-6=3x
18=3x
x=6

On both sides of equation 1 3x + 3 = 5, we get equation 1 3x = 2, which is based on

Minus 3
