Thank you so much, I didn’t really grasp this in intervention as my teacher explains fast and I do ask her how she got something n she’ll explain it but I still won’t get it! So I really like the way you tell what you do as you do each step. Thank you☺️

this is explained so much better than my math teacher😭😭😭 thank u sm

[vichithrakulasuriya]

Thank you so much Jay this really helped me in a last-minute exam, Is there an easier method in solving this?

Thank you soooo much Maths With Jay. This helped me understand this much better.

tysm was stuck on the first bit of the equation because my y wasn’t the subject but with your explanation i figured out how to make it the subject! in hindsight it was obvious but thanks for everything you do

Substitution is the best way of solving linear and non linear equations.

I used a quadratic formula and i gt it right can u always use it?

[abibott]

Are these questions common in the higher maths paper or do they appear rarely?

Sorry, I know this may be silly but how did 2×7/5-3 become -1/5?

[laibasoomro]

[pluto_xsun]

I understand the first couple steps but at 2:30 I get confused and give up

[bipensubba]

I am literally 12 years old and doing this math. I wouldn't consider myself a mathematical prodigy as I plan to pursue a career in medicine.
