"\\begin{Bmatrix}\n a \\\\\n b\n\\end{Bmatrix} = 1\/314*\\begin{bmatrix}\n 198 & -26 \\\\\n -26 & 5\n\\end{bmatrix}\\begin{Bmatrix}\n 1230 \\\\\n 6950\n\\end{Bmatrix}"

Expert's answer

"\\begin{Bmatrix}\n a \\\\\n b\n\\end{Bmatrix}=1\/314*\\begin{bmatrix}\n 198 & -26 \\\\\n -26 & 5\n\\end{bmatrix}\n\\begin{Bmatrix}\n 1230 \\\\\n 6950\n\\end{Bmatrix}"

"\\begin{Bmatrix}\n a \\\\\n b\n\\end{Bmatrix}=1\/314 *\\begin{bmatrix}\n 243540-180700 \\\\\n -31980+34750\n\\end{bmatrix}"

"\\begin{Bmatrix}\n a \\\\\n b\n\\end{Bmatrix}=1\/314*\\begin{bmatrix}\n 62840 \\\\\n 2770\n\\end{bmatrix}"

"\\begin{Bmatrix}\n a \\\\\n b\n\\end{Bmatrix}=\\begin{bmatrix}\n 31420\/157\\\\\n 1385\/157\n\\end{bmatrix}"
