6x-1 = 1169 6x = 1169+1 6x = 1170 x = 195
7
6x = 1 x = 1/6
-10 = 6x - 16, or 16 - 10 = 6x, or x = 1.
4x-1 = 6x-15 4x-6x = 1-15 -2x = -14 x = 7
5
6x-1 = 1169 6x = 1169+1 6x = 1170 x = 195
-5x+1 = 6x -5x-6x = -1 -11x = -1 x = 1/11
7
6x = 1 x = 1/6
-10 = 6x - 16, or 16 - 10 = 6x, or x = 1.
4x-1 = 6x-15 4x-6x = 1-15 -2x = -14 x = 7
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
x=4 y=1 Therefore, 6x+5y=? Just substitute, and get 6*4+5*1=29
If: 6x = 2/3 Then: x = 1/9
7x + 6x - 1 = 0 7x + 6x = 1 13x = 1 x = (1/13) This is not calculus btw. Its basic algebra.
9x-11 = 6x+1 9x-6x = 1+11 3x = 12 x = 4
