A system of linear equations is called a simultaneous linear equation with n unknowns. When ( x1 , ..., xn ) = ( a1 , ..., an ) satisfies all of the linear equations above, then ( a1 , ... , an ) is said to be a solution to ( 1 ). Let's try solving the following simultaneous linear equations. If we make 3 x (I) - 2 x (II), we get - y = -2. Therefore, y = 2. Substituting this into (I), we get x = -3. This method is called the addition and subtraction method. From (I), we get. Substituting this into (II), we get y = 2. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
一次方程式の系,をn元連立一次方程式という。(x1,……,xn)=(a1,……,an)が上のすべての一次方程式をみたすとき,(a1,……,an)は(1)の解であるという。次の連立一次方程式を解いてみよう。 3×(I)-2×(II)を作ると-y=-2。したがってy=2である。これを(I)に代入して,x=-3となる。この方法を加減法という。 (I)から,を得る。これを(II)に代入して,すなわちy=2が得られる。
