Steps to solving y=2x+3 x=y-8

1 answer:

3 0

First, plug in x=y-8 to y=2x+3
Next, it would be y=2(y-8)+3
Then, you need to distribute: y= 2y-16+3
After that, move 2y to the other side: -y= -13 (notice I also did -16+3)
Finally, divide negatives into both sides: y=13

Now to find x just plug in 13 to either of the equations: 13=2x+3
Then solve: x=5
So the FINAL answer is: (5,13)
Hope this helps!!!!!!!

Answer:

$x=22$

Step-by-step explanation:

According to the Alternate Interior angles theorem, the bottom left angle and the upper right angle have the same measure. Because they were formed from a pair of parallel lines crossed by a transversal one.

So, algebraically:

$5x+5=115\\ 5x+5-5=115-5\\ 5x=110\\ \frac{5x}{5}=\frac{115}{5}\\x=22$
