x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
Here is the work for that problem. 7x+6= 41 7x=41-6 (subtracting 6 from both sides) 7x=35 x=5
7x + 2 = -4 7x + 2 - 2 = -4 - 2 7x = -6 7x/7 = -6/7 x = -6/7
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
x2-7x+6 = (x-1)(x-6) when factored.
-7x + 6 + 7x - 2 = 4
42x
x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
Here is the work for that problem. 7x+6= 41 7x=41-6 (subtracting 6 from both sides) 7x=35 x=5
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
7x + 2 = -4 7x + 2 - 2 = -4 - 2 7x = -6 7x/7 = -6/7 x = -6/7
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
49x2 - 84x + 36 = (7x - 6)(7x - 6) or (7x - 6)2
x2-7x+6 = (x-1)(x-6) when factored.
7x+y=6
7x +y = 6
7x = 42 Divide both sides by '7'. Hence x = 42/7 x = 6 The answer!!!!!
