30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
x2 + 10x + 21 = (x + 3)(x + 7)
x=3
10x + 3 = 15 10x = 15 - 3 10x = 12 x = 1.2
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
x2 + 10x + 21 = (x + 3)(x + 7)
