Make up two equations, one that is true and one that is false. do not state which equation is true and which is false. your classmates will have to determine which is which. create an example of an open equation that uses the variable x and would require two or more steps to solve. your classmates will have to determine which value of x makes the equation true. answer and explain how to determine whether its false or not to me. i'll give brainliest

False equation:

8 - 7 + 6 = 99 - 78

1 + 6 = 99 - 78

7 = 99 - 78

7 = 21 → Answers don't match, so it's false.

True equation:

5 + 44 - 8 = (99 - 29) - 29

49 - 8 = (99 - 29) - 29

41 = 70 - 29

41 = 41 → Answer match, so its true

Equation with x:

5x - 7 = 4x - 7 + x

5x = 4x - 7 + x + 7

5x - x = 4x - 7 + 7

4x = 4x - 7+ 7

4x = 4x 0

4x - 4x = 0

0 = 0 → equation has been solved, and is considered a true equation

To know wether an equation is false or not, you have to wither solve and see the result or solve, get the results, subsitute all the vairables in the original euqation by the result, and see if the final result matches.

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

the two may have that, even a breakdown is probably offered
