Right, 3x-4x+9x-x
1. 3x - x = 2x
2. 9x-4x = 5x
- 2x +5x = 7x
is eassy
3a * * * * * Actually, it is 4a.
If you simplify the equation (s+t+s) the answer is 2s+t
When you simplify 49 plus 37 (49+37), the result is 86.
No 9xx-18x+36 9(xx-2x+4) xx-2x+4 (doesn't factor evenly)
13a
3x
3n.
2a² + 6a
4b
2x
9a + 1
