Solve equation? 3(-7+r)=-36
Minchanka [31]
Hey there! 

First we need to add by 21 on each of your sides

Like: 3r - 21 + 21 \\ \\ -36 +21

This gives us: 3r = 15

Now we have to divide by 3 on each sides

Like: \frac{3r}{3}  \\ \\ =  \frac{-15}{3}

Answer: r = -5

Good luck on your assignment and enjoy your day!

    x=93

B) x+20 = 93+20 = 113°. The adjacent exterior angle is 180 - 113 = 67°
