... and what is the question?
4x =20x=20/4x=5
y = 4x-3
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
The highest power of the variable is 2, so it is a second degree polynomial.
... and what is the question?
Parallel, the slope of the second equation is 4
(4x ^2 + 3) + (3x ^2 + 8) = ( 4x^2 + 3x^2 ) + (3+8) = 7x^2 + 11
2
4x-14
Multiply the first by 3 and the second by -2
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists
4x plus 7 plus 3x equals 19 plus xx = 2
x2+4x-12 = (x-2)(x+6) when factored
