7x + 6x - 1 = 0 7x + 6x = 1 13x = 1 x = (1/13) This is not calculus btw. Its basic algebra.
x=10 For the equation -9 - 6x +7x = 1 First, add nine to both sides to get all of the x's on one side -9 - 6x + 7x = 1 +9 +9 -6x +7x = 10 Then, combine like terms on the left side -6x+7x=10 x=10
6x
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
(7x - 1)(6x + 5)
6x
9x - 3(x + 13y) = 9x - 3x - 39y = 6x - 39y = 3(2x - 13y)
6x+x=7x
x - 7x = -6x
7x + 6x - 1 = 0 7x + 6x = 1 13x = 1 x = (1/13) This is not calculus btw. Its basic algebra.

7x + 7 + 6x - 9 = 13x - 2
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
6x+x = 7x
7x + 9 = 6x + 17 7x - 6x = 17 -9 x = 8
7x + 2 = 6x + 2 if and only x = 0.
