6x-7 = 3x+5 6x = 3x+12 (subtracting -7) 3x=12 (subtracting 3x) x=4 (dividing by 3)

A quadratic equation. If you wish to solve for x, you can do so as follows: -x2 + 6x + 7 = 0 x2 - 6x - 7 = 0 (x - 7)(x + 1) = 0 x ∈ {-1, 7}
If 6x-7=35 then 6x=35+7=42 and x=7
-6x+3 = -7-5x 7+3 = 6x-5x 10=x
6x-5 = 7, 6x = 7+5, 6x = 12, x = 2
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
6x + 3 = -7 -5x 6x + 5x = -7 -3 11x = -10 x = -10/11
6x+7 = -56x = -12x = -2
To solve 6x - 7 = 35, first you add 7: 6x - 7 + 7 = 35 + 7; i.e. 6x = 42. Then divide by 6: 6x/6 = 42/6, or x = 7.
6x-4+7=-5 6x+3=-5 6x=-8 x=-8/6 = -4/3
It is not possible to solve a single linear equation in two variables.
x= -8
6x - 8 + 2x - 5 = 7 - 2x ?
If: 6x-4+7 = 5 Then: x = 1/3
4x-1 = 6x-15 4x-6x = 1-15 -2x = -14 x = 7
x=5
