Question

A good many problems in the natural and social sciences as well as in engineering and the physical sciences deal with eqquations ralating twp sets of variables. An equation of the type ax=b,expressing the variable b in terms of the cariable x and used here because the graph of the equation above is asthaight line.similarly,the equation a1x1+a2x2+...+AnXn=b, expressing b in terms of the variables X1,X2,...Xn and the known constants a1,a2,...,An,is called alinear equation.In many applications we are given b and the constants a1,a2,...An and must find numbers x1,x2,...,Xn, called unknowns, satisfying (1).
A solution to alinear equation (1) is acequence of n numbers s1,s2,...,Sn,which has the property that (1) is satisfied when x1=s1,x2=s2,...Xn=Sn are subsituted in (1).

Answer 1

一个良好的许多问题在自然科学和社会科学以及在工程和物理科学处理eqquations ralating雷公藤多甙组的变数。方程的类型AX = B的，表示变量b的条款cariable x和用在这里是因为图方程以上asthaight line.similarly ，方程a1x1 + a2x2 +...+ AnXn = b的，表示b在变数象X1 ， X2之外， ...中立和已知常数格A1中，酶A2 ,...,一种被称为alinear equation.In许多应用中，我们得到b和常数格A1中，酶A2 ， ...一个和必须找到号码象X1 ， x2 ,...,中立，所谓的未知，满足（ 1 ） 。

解决alinear方程（ 1 ） acequence正一数， s2 ,...,锡，它的财产： （ 1 ）感到满意时， x1 =一， χ2 = s2中...差分=锡正在取代在（ 1 ） 。

Answer 2

我大概说说吧，不把每个字都写上来了，但是我敢保证对。也不会给你遗漏内容。请放心~

A good many problems in the natural and social sciences as well as in engineering and the physical sciences deal with equations ralating twp sets of variables.
说很多数学应用题里，讲的都是给两个变量，然后问等是关系的问题（也就是函数）

An equation of the type ax=b,expressing the variable b in terms of the cariable x and used here because the graph of the equation above is asthaight line.similarly
比如等式ax=b，说的就是变量b用x表示的结果，这里你还能发现图像应该是一条直线

the equation a1x1+a2x2+...+AnXn=b, expressing b in terms of the variables X1,X2,...Xn and the known constants a1,a2,...,An,is called alinear equation.
等式a1x1+a2x2+...+AnXn=b说的是b用变量x1, x2..xn和常数a1,a2,...,An表示的。这个叫线性等式。（中国教材具体怎么叫我就不知道了）

In many applications we are given b and the constants a1,a2,...An and must find numbers x1,x2,...,Xn, called unknowns, satisfying (1). 很多情况下b, 常数a1 a2 都是给出来的。求x1,x2,...,Xn，这个未知数什么情况下满足（1）。

A solution to alinear equation (1) is acequence of n numbers s1,s2,...,Sn,which has the property that (1) is satisfied when x1=s1,x2=s2,...Xn=Sn are subsituted in (1).
这个等式（1）结果将是n个数s1,s2,...,Sn。他们符合（1）的属性，就是说x1=s1,x2=s2,...Xn=Sn都能带回到（1）里
