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.

Solve the equaton 7 x equals 42?
if the equation was 7x = 42. The answer would be x = 6
What property of inequality would you use to solve the equation 14x equals 35?
None. Properties of inequalities are not that relevant when solving equalities.
How do you solve 75 percent of x plus 8?
75 percent is equal to 0.75, so the expression would look like (0.75x) +8. But if you do not know what it equals to it is not an equation and you can not solve it.
