Solution for 3x-5=20 equation:
3x - 5 = 20
3x = 20 + 5
3x = 25 (divide both sides by 3 to get x)
3x/3 = 25/3
x = 8.33333333333

Answer:
x=6
Step-by-step explanation:
I would look at this triangle and notice that x can be solved by setting up a ratio.
I generally put the short side of the triangle on the top and the long side on the bottom
4/x = x/9
You then cross multiply to get 36=x^2, or +-6=x
A length of a triangle cannot be negative, so we are left with the answer x=6
