- the first one is to take the addition of both equations. This allows you to solve x. y can be calculated easily after you have x.
- the second method is to represent x in the mean of y. I don't remember the Mathematics term so i will do it for you.
The first equation gives
take this into the second equation
\[5(20+3y)\div7 + 3y = 16\]
Of course the first method is much comfortable. Enjoy your math
Elimination is the 1st method u used & Substitution is the 2nd method
