4x + 20y
If: 9y-20y = 25 Then: y = -25/11
12x - 9y = 6, 12x + 20y = 64 29y = 58 y = 2 x = 2
16x
8x + 20y
ça ne marche pas...
It is a straight line equation that needs to be rearranged into slope-intercept form as follows:- 8x+20y = -80 20y = -8x-80 y = -0.4x-4
the answer to this is 4x + 57 (assuming that the 4x in the question is algebra)
1: 12x - 9y = 6 2: 12x + 20y = 64 Subtract 1 from 2: 29y = 58 y = 2. So does x.
4x^2 + 3
4x + 3 doesn't factor. It is in its simplest form.
(4x + 3)(4x + 3) (4x + 3)2
4x + 16 + 1 = 4x + 17 which cannot be factorised.
