Need help about the solution of an algebra math question with builder
The algebra math question takes up my limited energy and time, now I feel headache. Could someone help me to solve it with builder set notation?

Re: Need help about the solution of an algebra math question with builder
I will solve, you will put it into set notation.
Add 25 to both sides.
Add 2x to both sides.
Divide by 14.
Please finish up from there, or show some work indicating where you need help.
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.
