If you can answer them all i will give you brainliest, but any on any of them would be appreciated! 1) 2x + 7 = x + 9 x = ? 2) x + 10 + 5 = 2x + 7 x = ? 3) 2x + 3 = x + 7 x = ? 4) 3x + 1 = x + 19 x = ? 5) x + 1 + x = x + 9 x = ? 6) 2x + 5 = 3x + 2 x = ? 7) x + 21 = 4x + 3

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
