数学の連立方程式の問題です。 全てわからないので、やり方を教えていただきたいです！ テストも近いのでちゃんと理解しておきたいです。よろしくお願いします🙏 1枚目、問題。 2枚目、答えです。

fax + by = -13 2. 連立方程式{-2x+cy = 10 の正しい解は,x= -1, y = 2であるが,cの値を映し間違 えて解いたため,x=4,y=5が解として得られた。 a,b,cの値を求めなさい。 A,Bの2人が連立方程式 ax+3y=9 ( 4x+by=19を解いたが, Aは係数を間違えて4と書い たので,解がa=-2/2,y=5となった。また,Bは係数bを3と書き間違えたので、解 はx=5,y=-123となった。 a,bの値と正しい解を求めなさい。 ax + 3y = 9 (4x+by=19′ 3. Pさん, Qさんの2人が連立方程式 を解いたが, Pさんはαの値を間違 えたので解はx=-2,y=5となり,Qさんはbの値を間違えたので,解はx=5, y=-12となった。正しい解を求めなさい。 4. 連立方程式{3x+by=3 (6x + ay = 12. たために解がx = 3,y=2となった。 このとき, 正しい解を求めなさい。 (1) 5. 次の連立方程式を解きなさい。 (3) を解くところを間違えて連立方程式{ bx+ 3y = 3 f6x-ay=12. + x y x-2y+z=7 32x+y+3z=12 (x-3y +2z = 11 (2) (4) + MINIX 2/weit 2y ⅡI MIN 22 (2x+y+z=13 3x+2y+ z = 11 (x + y + 2z = 12 ”を解い

Many people think they are from the United States. Ayane thought they came from France because the name is "French" fries. So she answered, “France !” 15 That was wrong. Ellen said that French fries were originally from Belgium. Ayane was surprised. Ellen said, "When American soldiers went to Europe in World War I, they ate frites. Frites are popular food in Belgium. They're like French fries. The American soldiers liked them. The people in the area spoke French at that time, so the soldiers thought the area was in France. Later the 20 soldiers brought the food to the United States. So the name became French fries." That was an interesting story to Ayane. She didn't know that people speak French in some areas of Belgium. Ellen also can speak French. Ayane was surprised again. Then Ayane bought some waffles at the shop because she heard they were 25 very good. Ayane said, "Waffles are also originally from your country, right?" Ellen answered, "Yes. I've liked them since I was a child." Ayane heard that Ellen's dream is to run waffle shops in many countries. She hopes waffles will spread into more countries, so she is studying business at the university. Ayane said, "These waffles are nice! I like waffles, too. When you start your 30 waffle shop in Japan, can I help you at the shop?" Ellen answered, "Yes. Oh, the movie will start soon. Let's go, Ayane!" "Yes, let's go," Ayane said. Ayane was happy because she understood Ellen and her country better.
