p v = n r t
v = n r t / p
u = p r t r = u / p t
If there is one variable. Then put each variable equal to zero and then solve for the other variable.
the figures are similar. Find the value of each variable. solve
You set the two equations equal to each other and then solve for the variable.
-- You select an operation. -- You apply the same operation to each side of the equation. -- You keep doing both steps until the equation says (the variable) = (the value of the variable)
u = p r t r = u / p t
d = r t t = d / r
The answer will depend on the exact form of the formula.

It's not always to 'solve' as it is to 'simplify' EX: 15a + 3b = 45c simplifies to 5a + b = 15c
I have the feeling that you were looking to find a value for each variable in this equation. Unfortunately you can only solve for each variable in terms of the other variables in this equation.
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
Density=mass/volume V=D/M M=V*D

the substitution method in which you take each variable and you find out the value and then plug it into the original equation.the adding and subtracting method in which you subtract\add equations to take out a variable and you can figure out what the other variable is. then you also substitute that into that into the original variable
