It is equivalent to: 32x^2 +88x +21
4x plus 3 plus 2x is equivalent to expression 6x plus 3.
4x+7=9x+7 -5x=0 x=0
- X + 5Y - 4X + 7 gather terms - X - 4X ( same as - X + (- 4X ) 5Y 7 = - 5X + 5Y + 7 ----------------
4x plus 7 plus 3x equals 19 plus xx = 2
It is equivalent to: 32x^2 +88x +21
yes
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
3x+7=4x 7=4x-3x 7=x
4x plus 3 plus 2x is equivalent to expression 6x plus 3.
4x+7=9x+7 -5x=0 x=0
4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
- X + 5Y - 4X + 7 gather terms - X - 4X ( same as - X + (- 4X ) 5Y 7 = - 5X + 5Y + 7 ----------------
4x plus 7 plus 3x equals 19 plus xx = 2
4x+7-8x=17-4x+7=17-4x=10x = -5/2
4x plus 7
It is: y = -4x+12
