Answer:

r = 4

Step-by-step explanation:

19 = 7 - -3r

19 = 7 + 3r

Then you do Inverse Operations So you have to Subtract

19 - 7 = 12

12 = 3r

Then you do Inverse Operation So you have to Divide

12/3 = 4

19 = 7 - -3(4)

So Let's Make Sure That It Is Correct

19 = 7 - -3(4)

19 = 7 - -12

19 = 7 + 12

So 4 Is The Correct Answer

Solve for x <br> 4x+3 X-8

Karo-lina-s [1.5K]

We know this angle is a 90° or a right angle. So another words we know adding these 2 expressions equals to 90°.

(4x + 3) + (x - 8) = 90°

Remove the parentheses and combine the like-terms:

5x - 5 = 90°

Add 5 on both sides:

5x = 95°

Divide 5 on both sides

x = 19

You answer is x = 19.
