X^2=2y
To get x on its own you would have to square root both sides so you would end up with:
x=sqrt(2y)
Ax²+bx+c=0
The formula to solve for x is:

So for 3x²+13x+10=0, plug in the data
x=-13±√13²-4(3)(10) / 2(3)
x=-13±√169-120 / 6
x=-13±√49 /6
x=-13<span>±7 / 6
x=-13+7/6
x=-6/6

Answer:
x = 2
Step-by-step explanation:
First isolate the variable:
10x - 4 = 16
+4 +4
10x = 20
Then get x by itself:
10x = 20
x = 20/10
x = 10
If you want it estimated it would be .55 which would be 55/100 which would simplify to 11/20
