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
4x+7-8x=17-4x+7=17-4x=10x = -5/2
4x plus 7
I'm going to assume the polynomial in question is 2x7+(3-2x3)+(5x8-4x) Expanding out the polynomial: 2x7+3-2x3+5x8-4x Order the terms by powers of x: 5x8+2x7-2x3-4x+3 Since 8 is the highest power of x, the degree of the polynomial is 8.
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
3x+7=4x 7=4x-3x 7=x
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
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
4x + 7 - 8x = 17-4x + 7 = 17-4x = 24x = -6
