我想了一个数,如果我用这个数加上4,然后将结果乘以3,得到的答案和将这个数减去5再乘以2的结果相等.
a）用x表示这个数,写出一个关于x的方程.
b）解这个方称,找出我想的这个数.
a）3(x+4)=2(x-5)
b）解上面的方程
3x+12=2x-10
x=-22
设这个数A为x
然后第一问是
（x+4）*3=（x-5）*2
第二问是解方程，x=-22
如果我增加。4到号码，然后将结果乘以3，答案是减去5从数字，然后将结果乘以2的相同。。。 ）让x是数字，写一个方程。以x。的。，b）求解方程和数字，我想到的是。（请回答一个和B̶两个问题）
（（1+4）x 5）x 3=（X-5)x75x2
X=5.5
有1个数，加上4后再乘以3，其结果与将它减去5后再乘以2一样
a）设这个数为字母x，写出x的方程式
b）解方程式，以找到这个数
a) according to the question :we will get function 3(x+4)=2(x-5)
b) the number is -22.
Do you want the translation?
