Answers are in bold:

-1=3x-2

add 2 to both sides

-1+2=3x-2+2

1=3x

divide both sides by 3

1÷3=3x÷3

1/3=x

-3x=9

divide both sides by -3

-3x÷-3=9÷-3

x=-3

-10=-5x

divide both sides by -5

-10÷-5=-5x÷-5

2=x

I hope this is good enough:

Algebra I

Coordinates (x, y)
Midpoint Formula: $\displaystyle (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Step-by-step explanation:

Step 1: Define

Point P(1, 3)

Point Q(7, 7)

Step 2: Identify

P(1, 3) → x₁ = 1, y₁ = 3

Q(7, 7) → x₂ = 7, y₂ = 7

Step 3: Find Midpoint

Simply plug in your coordinates into the midpoint formula to find midpoint

Substitute in points [Midpoint Formula]: $\displaystyle (\frac{1+7}{2},\frac{3+7}{2})$
[Midpoint] Add: $\displaystyle (\frac{8}{2},\frac{10}{2})$
[Midpoint] Divide: $\displaystyle (4,5)$

Given that ∠ABC is bisected by BD→, m∠ABD = (-159 – 12x)°, and m∠DBC = (3x + 96)°, find x and m∠ABC.

laiz [17]

When anything is bisected, the two halves are equal. This means
(-159 - 12x) = (3x + 96)
-255 = 15x . . . . . . . . . . . . . add 12x-96
-17 = x

Then either of the smaller angles is
(3(-17) + 96)° = 45°

angle ABC is twice this value, or 90°.
