,答错率:73%
网考网试题解析:
试题答案: 答案解析:First, distribute the 8 to get 8y+8x=12. You can then multiply the second equation by -2 to isolate one of the variables, and rearrange the equations to line up the like terms: 8x+8y=12 -8x+6y=44 Add the equations together (note that the x terms cancel out): 14y=56 y=4 Now choose one of the original equations, substitute 4 for y, and solve for x. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
