1)
-4 + x/3 = 4
x/3 = 8
x = 24

2)
x - 6/-3 = 6
I’m assuming it’s:
(x - 6)/-3 = 6
x - 6 = -18
x = -12

Step-by-step explanation:

<h3> $\sec \alpha \sqrt{1 - \sin ^{2} \alpha } = 1$ </h3>

Prove the LHS

Using trigonometric identities

That's

<h3> $\cos ^{2} \alpha = 1 - \sin^{2} \alpha$ </h3>

<u>Rewrite the expression</u>

We have

<h3> $\sec \alpha \sqrt{ \cos^{2} \alpha }$ </h3>

<h3> $\sqrt{ { \cos }^{2} \alpha } = \cos \alpha$ </h3>

So we have

<h3> $\sec \alpha \times \cos \alpha$ </h3>

Using trigonometric identities

<h3> $\sec \alpha = \frac{1}{ \cos \alpha }$ </h3>

<u>Rewrite the expression</u>

That's

<h3> $\frac{1}{\cos \alpha } \times \cos \alpha$ </h3>

Reduce the expression with cos a

We have the final answer as

As proven

Hope this helps you

Answer:

-2

Step-by-step explanation:

→ -9x + 1 = -x + 17

→ -9x + x = 17 - 1

→ -8x = 16

→ x = -16/8

→ [ x = -2 ]
