What is the answer to 4 plus 6x equals 5 plus 3x plus 7?
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
If 6x-7 equals 3x plus 5 what is x?
6x-7 = 3x+5 6x = 3x+12 (subtracting -7) 3x=12 (subtracting 3x) x=4 (dividing by 3)
What is x2 plus 3x plus 7 equals 6x plus 18?
xx+3x+7=6x+18 xx+3x+7-(6x+18)=6x+18-(6x+18) xx-3x-11=0 Factors of -11: 1,-11 -1,11 Doesn't factor evenly, use quadratic
