people think i'm super smart. like nope i'm not i just take good notes and therefore i figure out how to do stuff ;p (math is literally just a puzzle containing formulas. understand the formulas and you will understand math!)

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

To diagonalize an nxn matrix a means to find an invertible matrix p and a diagonal matrix d such that a pdp d p ap or [1 3 dh epap 3 let a=-3 -5 -3 3 3 1 step 1: find the eigenvalues of matrix a "2's" step 2: find the corresponding eigenvectors of a step 3: createp from eigenvectors in step 2 step 4 create d with matching eigenvalues.

The sum of five and a number n is at least 12
