Equality Properties
- Multiplication Property of Equality
- Division Property of Equality
- Addition Property of Equality
- Subtraction Property of Equality
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify given.</em>
y = 3x - 2
y = 3
<u>Step 2: Solve for </u><u><em>x</em></u>
- [Equation] Substitute in <em>y</em>:
3 = 3x - 2 - [Addition Property of Equality] Add 2 on both sides:
5 = 3x - [Division Property of Equality] Divide 3 on both sides:
5/3 = x - Rewrite:
x = 5/3
∴ the value of <em>x</em> when <em>y</em> = 3 is equal to 5/3, or approximately 1.67.

Answer:
Step-by-step explanation:
Here, given :
sin 2 x - 2 sin x = 2 .... (1)
Now, by <u>TRIGONOMETRIC IDENTITY</u>:
Sin 2Ф = 2 SinФ CosФ
⇒ sin 2 x = 2 sin x cos x
Putting back the value in (1), we get:
sin 2 x - 2 sin x = 2 ⇒ (2 sin x cos x) - 2 sin x = 2
or, 2( sin x cos x - sin x) = 2
or, sin x cos x - sin x = 1
or, (sin x) ( cosx - 1) = 1
⇒ Sin x = 1 / ( Cos x - 1)
Hence,
Answer:
y=7x-6
Step-by-step explanation:
Use point-slope equation.
y-y1=m(x-x1)
y-8=7(x-2)
y-8=7x-14
y=7x-6
