This doesn't simplify unless you use the quadratic equation. If using the quadratic, the answer is 16 + -Ö 69 /5 In words, sixteen plus or minus the square root of sixty-nine divided by five

6x + 9 + 2x = 8x + 9
8x - 4x + 7 = 94x + 7 = 94x = 9-74x = 2x = 4/2x = 1/2x = 0.5
No, it has factors... 4x2 + 8x -21 = (2x+7)(2x-3)
4(2x-3)+7=8x8x-12+7=8x-8x..........-8x-12+7=0+12.....+127=12-7...-7No Solution:0≠54(2x-3+7)=8x8x-12+28=8x-8x............8x-12+28=0+12.......+1228=12-28...-28No Solution: 0≠-16
(2x + 1)(4x - 7)

8x-7 plus 2x equals 6 plus 5x plus 2?
out = in+in; /* 2x */ out += out; /* 4x */ out += out; /* 8x */ out -= in; /* 7x */ or out = (in<<3) - in; /* 8x - x */
8x + 38 = 2x + 2 The first thing you want to do is get all the variables on one side and all the stand-alone numbers on the other side. To do this, you just do the opposite of what the sign is (Ex: Since it is "plus 38" on the left side, to get it to the right we subtract 38) 8x = 2x + 2 -38 Now you can simplify the right side: 8x = 2x -36 And then you want to get the variables on the left side of the problem. So since 2x is positive, you want to subtract 2x from both sides of the equation. 8x - 2x = -36 Simplify the left side: 6x = 36 And then from there you can divide both sides by 6. x = 6
This will simplify to 27 - 12x, assuming the original equation was 7-34-2x-10x.* * * * *No, it will not! If the assumption is correct, it will simplify to -27-12x.
