Answers

Answer:

Pic 1: [tex]x=31[/tex]

Pic 2: [tex]x=20[/tex]

Step-by-step explanation:

Picture 1:

[tex]2x+x-3=90\\3x-3=90\\3x=93\\x=31[/tex]

First, add the 2x and x together for 3x

Then add 3 to both sides of the equation

Finally, divide each side by 3.

Picture 2:

[tex]7x+x+20=180\\8x+20=180\\8x=160\\x=20[/tex]

First, add 7x and x together for 8x

Then, minus 20 from both sides of the equation

Finally, divide each side by 8.

Step-by-step explanation:

First picture

We can make an equation with this

2x+x-3=90

3x=93

x=31 degrees

Second picture

We can make and equation

7x+x+20=180

8x=160

x= 20
