65x = 104 x = 104/65 = 8/5 or 1 and 3/5
(7x - 8)(2x - 7)
False12x - 66 = 3x + 912x - 3x = 9 + 669x = 65x = 7.22Check:12(7.22) - 60 + 6 = 1(7.22) + 9 + 2(7.22)86.64 - 66 = 7.22 + 9 + 14.4420.64 = 30.66
If x = 10 Then: (33*10)+(32*10)+7 = 657 So: 33x+32x+7 = 657 Collect like terms and note that 7 is now -7 because it has moved over to the other side of the equation. 65x = 657-7 65x = 650 Divide both sides of the equation by 65 to find the value of x: X = 10
If you mean y = -65x-4 then the parallel equation is y = -65x-66

The LCM is 455x.
If you are looking for the value of x:5x + 14 = -65x = -6 - 145x = -20x = -20/5x = -4Substituting the value of x to the original equation:5(-4) + 14 = -6-20 + 14 = -6-6 = -6Therefore the value of x is correct.
(13x + 39)(x + 2) * * * * * Don't you think it might, instead, be (13x - 39)(x - 2)? Multiply it out, and see!
.65x(100/100)=65/100
That could mean two different equations, so I'll solve both.1. (√5x)+ 7 = 13(√5x)= 65x = 36x = 36/5= 7 1/52.√(5x+7) = 135x + 7 = 1695x = 162x = 162/5= 31 2/5
