Answer 1

`x+100+3x=180\\4x=80\\x=20`

Answer 2

`\text{Hey there!}`

`\text{Note: This line/triangle have a degree of 180}`

`\text{Firstly, you have to set up your equation, which is:}`
`\text{x + 100 + 3x =180}`

`\text{Next, COMBINE your like terms: x + 3x}`

`\text{x + 3x = 4x (Side note: the x by itself is equal to a(n) invisible 1)}`

`\text{100 stays the same because it doesn't have a like term}`

`\text{4x + 100 = 180}`

`\text{Thirdly, we have to SUBTRACT by 100 on your sides:}`
`\text{4x + 100 - 100}\\\text{180 - 100}`

`\text{Cancel out: 100 - 100 because it equals to 0}`

`\text{Keep: 180 - 100 because it helps us solve for our answer}`

`\text{Our new equation becomes: 4x = 80}`

`\text{Fourthly, we have to DIVIDE by 4 on each of your sides:}`
`(4x)/(4)=(80)/(4)`

`\text{Cancel out:}(4x)/(4)\text{ because it gives us the result of 1}`

`\text{Keep:}(80)/(4)\text{ because it helps us solve for our answer}`

`\uparrow\text{If you solved the kept answer correctly you would have your answer for x}`

`\boxed{\boxed{\bf{Answer: x = 20}}}\checkmark`

`\text{Good luck on your assignment and enjoy your day!}`
