We can solve simple algebras by reversing the mathematical symbols and shifting the number or unknown to the other side of the equation.
+ turns to -
x turns to ÷
(or vice versa)

So, first step to solve this,
shift +1 to the other side, turn it into -1.
3x = 3 - 1
3x = 2
Now, shift x3 to the other side, turn it into ÷3.
x = 2 ÷ 3
x = 2/3 (or 0.6666666...)

need help. solve for y. try factoring first if not possible or difficult use quadratic formula. y²-6y+6=0

lbvjy [14]

$y^2-6y+6=0\\ \\a=1 , \ b=-6, \ c=6 \\ \\\Delta =b^2-4ac = (-6)^2 -4\cdot1\cdot6 = 36-24=12\\ \\\sqrt{\Delta }= \sqrt{12}=\sqrt{4\cdot 3}=2\sqrt{3} \\ \\x_{1}=\frac{-b-\sqrt{\Delta} }{2a}=\frac{6-2\sqrt{3}}{2 }=\frac{2( 3- \sqrt{3})}{2}= 3- \sqrt{3}$

$x_{2}=\frac{-b+\sqrt{\Delta} }{2a}=\frac{6+2\sqrt{3}}{2 }=\frac{2( 3+ \sqrt{3})}{2}= 3+ \sqrt{3}$
