Please help me and can you write an explanation too please.

Answer:
[tex]\Huge\boxed{x=29}[/tex]
Step-by-step explanation:
Hello There!
Once again the angles shown are supplementary angles meaning that the sum of the measure is equal to 180
so we use this equation to solve for x
180 = x + 4x + 35
step 1 combine like terms
x + 4x = 5x
now we have 180=5x+35
step 2 subtract 35 from each side
180 - 35 = 145
35 -35 cancels out
now we have 145 = 5x
step 3 divide each side by 5
5x/5=x
145/5=29
we're left with x = 29
Answer:
(×+35)+4×=180°[sum of angles in a str. line ]
5×=180-35
5×=145
5x/5=145/5
x=29
