4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
If 4x + 7 = 3... then x must equal -1
4x - 7 = 5 + 7x x = -4
x+5+3x-7+9x+3-4x Collect like terms: 9x+1
It is a mathematical equation, usually written like this: 5x - 7 + 2x = 3x - 2 + 4x
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
