It makes the addition easier if you combine like terms like the two 1/2s and then make them all have the denominator of 12 (changing the numerators to equal it out)

give brainliest please!
hope this helps :)
so these two angles add up to 180 degrees
7x -3 + 12x -7 = 180
7x+12x=180+7+3
19x=190
x=10
to check if this is true we can input 10 for x in each side.
7(10)-3 = 67
12(10)-7 = 113
113+67 = 180
Answer:
(x) = ![\frac{x+4}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B4%7D%7B2%7D)
Step-by-step explanation:
let d(x) = y and rearrange making x the subject, that is
2x - 4 = y ( add 4 to both sides )
2x = y + 4 ( divide both sides by 2 )
x = ![\frac{y+4}{2}](https://tex.z-dn.net/?f=%5Cfrac%7By%2B4%7D%7B2%7D)
Change y back into terms of x, so
(x ) = ![\frac{x+4}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B4%7D%7B2%7D)
