Thank you for the opportunity to help you with your question!

4x-7 >= 1

add 7 to both sides(you can think of it as if you take 7 to the other side and change its sign. This way of thinking will make you faster)


(*4x >=1+7 ( you can write this quickly if you think of taking 7 to the other side and change its sign))

so you will have

4x >= 8

then divide both sides by 4

4x/4 >=8/4

x >= 2

Please let me know if you need any clarification. I'm always happy to answer your questions.
