<u>Step 1: Define</u>
-4x + 3y = -2
y = x - 1
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -4x + 3(x - 1) = -2
- [Distributive Property] Distribute 3: -4x + 3x - 3 = -2
- Combine like terms: -x - 3 = -2
- [Addition Property of Equality] Add 3 on both sides: -x = 1
- [Division Property of Equality] Divide -1 on both sides: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em> [Original Equation]: y = -1 - 1
- Subtract: y = -2

-3+3. (-4)=16
-3-12=16
-15=16 false
4x+7+2x-5+4x-6 or 10x+7-6-5
Answer:
B. 16 degrees
Step-by-step explanation:
Because all of the angles in a triangle add up to 180 degrees, you can set up an equation for this problem:
2x - 10 + 4x + 46 + 3x = 180
Start by consolidating everything by adding like terms.
9x + 36 = 180
Then subtract 36 from both sides.
9x = 144
Then divide both sides by 9 to get your x.
x = 16
The required solution is ∠RQT = 202° and ∠QTS = 51°

<h3>What is a cyclic quadrilateral?</h3>
A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle. It is also called as inscribed quadrilateral.
Its main property is that the sum of opposite angles of inscribed quadrilateral is always 180 degrees.
Now, the given circle has a cyclic quadrilateral QRST in which it is given that ∠RQT = 202° and ∠QRS = 129°
Since,sum of the opposite angles of a cyclic quadrilateral = 180°
⇒∠QTS + ∠QRS = 180°
⇒ ∠QTS + ∠129° = 180°
⇒ ∠QTS = 180° - ∠129°
⇒ ∠QTS = 51°
Hence,the requires angles are ∠RQT = 202° and ∠QTS = 51°.
