2x2 - 9x + 3 = 0
Using the quadratic formula:
x = [9 ± sqrt(92 - 4*2*3)]/(2*2)
= [9 ± sqrt(81-24)]/4
= [9 ± sqrt(57)]/4
= 0.36254 or 4.13746 (to 5 dp)

How would you solve x equals 2 to find the y intercept?
You would take 2 and replace it for x in your other equation and solve.
Find the equation of x plus 3y equals 4?
This equation is unsolvable since there are two unknowns and only one equation. You would require a second equation in order to solve it.
How would use solve the system of equation x plus 3y equals 23 by using substitution?
You'd need another equation to sub in
What number would you add to both sides of the equation x - 8 equals 17 to solve for x?
Add 8
9x-5y-4 equals 0 Solve for y?
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.

What times 8 equals 12?
To solve this, you should first write it as an equation (where 'x' is the unknown value):8x = 12Then you can solve for x:8x =12X = 12/8X=1.5
What number would you add to both sides of the equation x - 8 equals 17 to solve for x?
Add 8
What is a multi step equation that equals 13?
13
How do you solve x equals t-yz?
Because this equation has four variables, it would require four unique equations involving only these four variables to solve.
9x-5y-4 equals 0 Solve for y?
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
What plus 5 equals 0?
The equation you are looking for is x + 5 = 0. To solve for x, you would subtract 5 from both sides of the equation. This would give you x = -5. Therefore, -5 plus 5 equals 0.
