I’ve been having trouble with these all week!

Step-by-step explanation:

so you will move constant to the right side and change the sign. 72x=223-7

then you will subtract the numbers 72x=223-7 and that will give you 72=216

then you will divide both sides by 72  and that will give you

3

Step-by-step explanation:

1. subtract 7 on both sides since 7 and 223 do not have variables next to them

2. rewrite as 72x=216

3. divide by 72x on both sides

4. x=3

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
