Solve these simultaneous equations by elimination: a. 2x y = 6 4x + 3y = 22
Question:
Solve these simultaneous equations by elimination:
a. 2x − y = 6
4x + 3y = 22
b. 7x + 3y = 16
2x + 9y = 29
c. 5x + 2y = 6
3x − 10y = 26
d. 2x − y = 12
6x + 2y = 21
e. 3x − 2y = −6
6x + 3y = 2
f. 3x + 8y = 33
6x = 3 + 5y

I have worked with both teachers and students to offer specialized help with everything from grammar and vocabulary to challenging problem-solving in a range of academic disciplines. For each student's specific needs, I can offer explanations, examples, and practice tasks that will help them better understand complex ideas and develop their skills.
I employ a range of techniques and resources in my engaged, interesting tutoring sessions to keep students motivated and on task. I have the tools necessary to offer students the support and direction they require in order to achieve, whether they need assistance with their homework, test preparation, or simply want to hone their skills in a particular subject area.
