What is 20x+3=5 what is x.
What is 4-x=9 what is x.
If you can anser these i have a lot more i`m having problems with please help.
Simple. Just get x to stand alone.
20x=5-3 Subtract 3 from both sides.
x=2/20 Divide 20 on both sides.
I'll show you how to do these problems so that you'll learn how to do the rest of your problems
Subtract 3 from both sides of the equation.
20x = 2
Divide both sides by 20
x = 2/20
x = 1/10
Add x to both sides.
5 = 9 + x
Subtract 9 from both sides.
4-9 = x
-5 = x
