Hello there!
[tex]92 = -4(2r - 5)\\[/tex]
Explanation:
↓↓↓↓↓↓↓↓↓↓↓↓
First you had to switch sides.
[tex]-4(2r-5)=92[/tex]
Then you divide by -4 from both sides of the equation.
[tex]\frac{-4(2r-5)}{-4}=\frac{92}{-4}[/tex]
Simplify
[tex]2r-5=-23[/tex]
Next you had to add by 5 from both sides of the equation.
[tex]2r-5+5=-23+5[/tex]
Simplify
[tex]2r=-18[/tex]
You can also divide by 2 from both sides of the equation.
[tex]\frac{2r}{2}=\frac{-18}{2}[/tex]
Simplify it should be the correct answer.
[tex]r=-9[/tex]
Answer⇒⇒⇒⇒⇒r=-9
Hope this helps!

First to get rid of the parantheses we must multiply -4 times any number inside of the parantheses.
92=-4(2r-5)
92=-8r+20
Next subtract 20 from both sides
92=-8r+20
72=-8r
Divide both sides by -8
72=-8r
72/-8=-8r/-8
-9=r
Our final answer is -9
Hope this helps!
