To solve the first equation, we need to isolate the variable x:
865 - x = 270 + 365Combine like terms:865 - x = 635Subtract 865 from both sides:-x = -230Divide by -1:x = 230
Therefore, x = 230.
To solve the second equation, we need to isolate the variable x:
45 + 30 + x = 100Combine like terms:75 + x = 100Subtract 75 from both sides:x = 25
Therefore, x = 25.
