9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3

Split it into two cases. First - 6x-5 is positive(greater or equal to zero): Equation will get following form: 6x-5 <= 5 This resolves to x <= 10/6. Second case - 6x-5 is less than zero: Equation will get following form: -6x+5 <= 5 This resolves to x >= 0. As we can see, x has to be both greater than zero and less than or equal to 10/6, and this is our answer. 0 <= x <= 10/6

8x + 11 = 33 + 6x 8x - 6x = 33 - 11 2x = 22 x = 11
The expression is: y/6x
If you mean: 4y-6x = 120 then y = 1.5x+30 whereas 1.5 is the slope and 30 is the y intercept

7x+8-x-7 6x+1
6X + 33(2X + 1)==========( all the factoring I see to do here )
The correct problem is: 5(7+8)divided by 6x(-2)
If you mean: 6x-y = 33 and 6x+3y = 45 So by eliminating 6x in both equations by subtracting: 4y = 12 => y =3 Therefore by substitution: x = 6 and y = 3 Remember: --y+3y = 4y
