I have a problem in this form:

a₁x₁₊a₁x_1+...a_nx₁ +(x₁)³ = b₁

a₁x₂₊a₁x_2+...a_nx₂ +(x₂)³ = b₂

..........................................

a₁x_n+a₁x_n+...a_nx_n +(x_n)³ = b_n

Here, x_1,x_2,.......,x_n  are unknowns, a₁,a₂,...,a_n and b₁,b₂,...,b_n are known contants.

Is there a possible way to find unknowns?
