10x - 5x + 5x = 10x
10x + 41y142x + 2y
-10x -9
-10x + 5x = -5x
3x + 12 + 10x = 13x + 12
It is: 10x+14 simplified
6 + 10x + 3 = 9 + 10x
10x + 7 + 3x = 13x + 7
10x-7+x+7 = 11x
10x plus 40 is 50x.10+40=50 and then you just add the x so:10x+40=50x
-3x + 10x - 5 + 26 = 7x + 21
2x2 + 10x + 25 is a quadratic expression. It describes a parabola.
