I got two massive equations with two variables, and vpasolve can not find the solution because that commend search for an accurate answer, which does not exist. I want to get the nearest value of the variables that solve the equations. For example, I am satisfied with 90% accurate solutions.
can I add an accurate aspect in the commend vpasolve?
if not, what command or simple method can I use?

The enhanced accuracy in contrast to other methods is never the reason why vpasolve fails to find a solution.
To get a useful answer from the forum, we have to see your equations.

I am not certain what problem you are having.
One option is to solve the equations and then use vpa on the solutions.
Example —
syms x
Eqn = x^5 + 2*x^4 + 10*x^3 - 3*x^2 - 110*x + 1
xs = solve(Eqn,x)
xsn = vpa(xs)
