Answer:
Below in bold
Step-by-step explanation:
-3(8x - 2) = 9 - 21x
~Divide -3 to everything
8x - 2 = -3 + 7x
~Add 3 to both sides
8x + 1 = 7x
~Subtract 8x to both sides
1 = -x
~Divide -1 to both sides
-1 = x
Note that this isn't the most used way to solve equations because you would typically use distribution to simplify the left side.
Best of Luck!
An angle that is *bisected* is an angle that is *cut in half*. What angle is half of 22 degrees?
Answer: r=1/2
Step-by-step explanation:
To solve just isolate y from 2x-y=-1 to get y=2x+1. Then substitute y=2x+1 into 3x-2y=1. So it should be this: 3x-2(2x+1)=1. Distribute to get 3x+4x-2=1. Add the x's to get 7x-2=1, add two to both sides to get 7x=3 and divide to finally get x=3/7.
