4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
the sum of -5 and 3x
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
(3x - 5)5= (3x + -5)5= (5C0)(3x)5(-50)+(5C1)(3x)4(-5)1+(5C2)(3x)3(-5)2+(5C3)(3x)2(-5)3+(5C4)(3x)1(-5)4+(5C5)(3x)0(-5)5= (1)(243x5)(1)+(5)(81x4)(-5)+(10)(27x3)(25)+(10)(9x2)(-125)+(5)(3x)(625)+(1)(1)(-3125)= 243x5 - 2,025x4 + 6,750x3 - 11,250x2 + 9,375x - 3125
