WebFor solving the system of equations using the substitution method given two linear equations in x and y, express y in terms x in one of the equations and then substitute it in 2nd equation. Consider 3x − y = 23 → (1) 4x + 3y = 48 → (2) From (1), we get: y = 3x − 23 → 3 Plug in y in (2), 4x + 3 (3x − 23) = 48 13x − 69 = 48 13x = 117 ⇒x = 9 WebRuling out the solution (0,0,0), we have xyz = 0. WLOG x ≥ y ≥ z, then n(x +y +z) ≤ 3nx and so we must have yz ≤ 3n, in particular max(y,z) ≤ 3n. So there are finitely ... How to get from … mckinney foundation indiana
