What is the sum of x-3 and 2x plus 7?
Oh, dude, you're hitting me with some math now? Alright, let's break it down. So, we have x - 3 + 2x + 7. Combine like terms, and we get 3x + 4. That's your sum, my friend. Math can be fun... sometimes.
What is the answer to 2x plus 3 equals 4x-7?
2x + 3 = 4x - 7 <=> 4x - 7 = 2x + 3 <=> 2x = 10 <=> x = 5 - - - 2x + 3 = 4x - 7 Take the 2x from each side of the equation. 3 = 2x - 7 Get the numerals together 7 + 3 = 2x Therefore 10 = 2x Therefore 5 = x
Solve 2x plus 3 equals 7?
2x+3 = 7 2x = 7-3 2x = 4 x = 2
