数学里change the subject of the following formulae into the letter in the square brackets
这里涉及数学中的主项变换,可译为:将下列公式中的主项转换为方括号中的字母.
例如,
P=q(r-1)+2r [r]

即r=?
解:
P=qr-q+2r*r
P+q=qr+2r*r
P+q=r(q+2r)
(P+q)/(q+2r)=r
转换主项 r=(P+q)/(q+2r)

将下面公式中对应的项变成小括号中的字母 。

翻译:将下列公式中的项目变换成方括号内的字母。

要学着问问题。这样的问题如果给一个实际的题目,人家帮你解一题就一目了然了
