Which of the following statements are true? Select all the correct answers. If you rewrite a one-variable linear equation and see a statement like \( 4=4 \) or \( 4 a+6=4 a+6 \), then the equation has infinitely many solutions. B If you rewrite a one-variable linear equation and the variable terms are the same on each side of the equation, then you can solve the equation and find the value of the variable. C If a one-variable linear equation has one solution, then every value of the variable makes the equation true. D If both sides of a one-variable linear equation have the same variable term and different constant terms, then the equation has infinitely many solutions. E If a one-variable linear equation has no solution, then no value of the variable will make the equation true.

The Deep Dive
When you simplify a one-variable linear equation and end up with an identity like \( 4=4 \) or \( 4a+6=4a+6 \), it’s like finding a treasure chest with an infinite stash of gold—meaning the equation has infinitely many solutions! These scenarios indicate that every number you plug in will fulfill the equation. On the flip side, if you get an equation such as \( 4a + 6 = 4a + 7 \), where the variable terms are identical but the constants differ, it's like trying to fit a square peg into a round hole—this equation has no solution. It creates a contradiction, which is impossible to satisfy, so no value can ever make the equation true!
