Here's the equation: 4-3x=22
Now solve for x.
I'll let you do the algebra, but the answer is x=-6.

Start by just writing in symbols what the sentence is saying:
4 - (is decreased) 3 * x (three times a number) = (the result is) 22
so 4 - 3x = 22 subtract 4 from each side
-3x = 18 divide both sides by -3
x = -6
