Best Answer

To solve a formula, you need to isolate the variable you are solving for by performing inverse operations. Start by simplifying the formula using the order of operations (PEMDAS), then move terms around to isolate the variable. Perform the inverse operations (addition/subtraction, multiplication/division) to solve for the variable. Remember to perform the same operation on both sides of the equation to maintain equality.

if you want to work out what x is this how you do it:

3(3+x)=99

9+x=99 (expand the brackets)

x=90 (-9)

remember what you do on one side you have to do it one the other

How do I sovle -0.2x2 plus 12x plus 11 equals 0?

-0.2x2+12x+11 = 0 Using the quadratic equation formula will give you two solutions which are: x = 30 + the square root of 955 = 60.90307428 to 8 decimal places. or: x = 30 - the square root of 955 = -0.90307428 to 8 decimal places.
