Well put it in correct order : <span>4z-111+3z-12=300.
</span><span><span><span><span><span>4z</span>−111</span>+<span>3z</span></span>−12</span>=300</span>

<span><span><span><span>7z</span>−123</span>+123</span>=<span>300+123</span></span><span><span>
7z</span>=423</span>
<span><span><span>7z</span>7</span>=<span>423/7</span></span><span>

Your answer is z=423/7.
Hoped I helped!
Answer:
36
Step-by-step explanation:
Total number of packages = 12
Each package contains 3 pens
SO we can write the equation as follows
3 * 12 = 36
so the total no of pens in a box = 36
Yes it is and it equals 703 when divided
Remember: We have to work from either the LHS or the RHS.
(Left hand side or the Right hand side)
You should already know this:
1.
2.
3.
<span>So, our question is:
</span>
Plug in the first two identities I gave you.
Apply the first identity I said you needed to know on 1/(tan θ). We should get:
Multiply the first fraction by sinθ, on both the numerator and denominator.
Multiply the second fraction by cos<span>θ, on both the numerator and denominator.
</span>
Now, use the third identity I said that you needed to know to simplify the numerator.
LHS = RHS
<span>
Therefore, identity is verified.</span>
