Y= –3x + 6

y= 9

what is the solution to the system of equations?

(–21, 9)

(9, –21)

(–1, 9)

(9, –1)

(-1,9)

Step-by-step explanation:

To find out the solution we substitute the value of y in the first equation

given y =9

we plug in 9 for y in the first equation

Subtract 6 on both sides

Now divide both sides by -3

The value of

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
