Answer:

x=10 or x=-2

Step-by-step explanation:

add 28 to both sides

(x-4)^2=36

sqrt both sides

remember to get positive and negative roots

x-4=+/-6

add 4 to both sides

x=4+/-6

x=4+6 or x=4-6

X + 3y = -3 solve for Y (ex. y= 3 + 5x

AnnyKZ [126]

Answer:

y = -1/3x - 1

Step-by-step explanation:

Let's solve for y.

Step 1: Add -x to both sides.

x+3y+−x=−3+−x

3y=−x−3

Step 2: Divide both sides by 3.

y=-1/3x-1

$\frac{-1}{3} x-1$
