What is the solution to this system of linear equations? 2x + 3y = 3 and 7x - 3y = 24

2x + 3y = 3 ... (i)

7x - 3y = 24 ... (ii)

Adding (i) and (ii) we get;

9x + 0 = 27 , 9x = 27 , x = 3

Replacing x=3 in equation (i) we get;

2(3) + 3y = 3

3y = 3 - 6 , 3y = -3 , y = -1

The solution (x,y) of the system of equations above is (3,-1)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
