Answer:
two real, unequal roots
Step-by-step explanation:
y is definied as y = 3x - 1. Substitute 3x - 1 for y in xy = 9, obtaining:
x(3x - 1) = 9. Then:
3x^2 - x - 9 = 0. In this quadratic, the coefficients are a = 3, b = -1 and c = -9.
Calculating the discriminant b^2 - 4ac, we get (-1)^2 - 4(3)(-9), or 1 + 108, or 109. Because the discriminant is positive, we have two real, unequal roots.
Your answer is, get the variable by itself.
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.

Answer:
1/3* (9x-6) = 2x+3
⇒ (1/3)(9x)- (1/3)*6 = 2x+3 (distributive property)
⇒ 3x - 2= 2x + 3
⇒ (3x-2x) -2 = (2x-2x) +3
⇒ x-2=3
⇒ x +(-2+2) = 3+2
⇒ x= 5.
