Solve 7 + 2(4 - x) = 7 - 2(x - 4). a. x=12 b.x=4 c. This is an identity and is true for all real numbers. d. there is no salution
Subtract 7 from both sides, you get 2(4-x) = -2(x-4) It stands for all numbers Its c
Sorry for giving wrong answer at first..bit its C
in other words, no matter the number that x is, the equation will be true so c
