You can do addition and substraction operations with polynomials similarly as with simple real numbers.
First of all you have to open brackets and then you can add numbers (-7-4=-11). Then the result is following:
<h3>Hey there! </h3><h3>The second "
" is has invisible
</h3><h3>Here, this is what I meant:
</h3><h3>So, now your equation looks like this:
</h3><h3>Add the exponents:
</h3><h3>Therefore your answer should be:
</h3><h3>(Note: there's many ways to solve these types of equations, I just gave you the basic method) </h3><h3 /><h3>Good luck on your assignment and enjoy your day! </h3><h3>~

First one hope this helps!
1/2 t-4(2+t)=20
1/2 t-8-4t=20
least common multiple=2
t-16-8t=40
-7t=40+16
-7t=56
t=56/-7=-8
Answer: t=-8
To check
-8/2 - 4(2-8)=-4-4(-6)=-4+24=20
-13 because 6 x 2 = 12 plus x = -13 x represents 1 btw
