70 + x + 55 + 30 = 180

sergiy2304 [10]

Answer:

x=25

Step-by-step explanation:

First, we add all like terms. Then, we solve for x.

$70+x + 55 + 30 = 180\\x+70 + 55 + 30 = 180\\x+155=180\\x=25$

We can rearrange some things because order does not matter with addition. Next, we just use basic equation solving techniques.
