Answer:

(x - 9)² = 87

Step-by-step explanation:

Move the -6 to the other side

x² - 18x = 6

The number you add to each side is (b/2)²

(b/2)² is (-18/2)² = 81

x² - 18x + 81 = 87

(x - 9)² = 87

Need to solve for Y by filling in the blanks<br>(y +44)°, 86, (3y)°​
lapo4ka [179]
Answer:

1.89

Solution:

We have -44x - 86 = -3

First, we move the non x terms to the RHS of the equation. To do this, we add 86 to both sides.

Note: if a = b, then a + c = b + c
Therefore, -44x - 86 + 86 = -3 + 86

or, -44x = 83

Next, divide both sides by -44, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c
-44x
-44
=
83
-44

or, x = -1.89
