8-1 Algebra to 9th Grade.

Algebra Level 2

Like I am in 8th Grade 8-1 (12/21/20) I will give you an Algebra problem.

5 (- 3 x - 2) - (x - 3) = - 4 (4 x + 5) + 13

-15 x - 10 - x + 3 = - 16 x - 20 + 13

  • 16 x - 7 = - 16 x - 7 So what is the answer? I made it easy for people who don't know this. Don't mind the bullet point that not part of the problem.


The answer is 0.

2 solutions

The following solution involves the following equations and their corresponding reasons based on deductive reasoning.

Add 16x + 7 to both sides and write the equation as follows 0 = 0. The above statement is true for all values of x and therefore all real numbers are solutions to the given equation.

In the last line of the provided math, a negative sign is changed to a bullet point. I agree that any value of x x is part of the solution set. The answer should not be x = 0 x=0 .

oh, that not part of the problem, when I edit the problem the bullet point disappears but when I post it again shows the bullet point, just pretend it is not there.

No, it still has the intent of and looks like a negative sign. The RHS and LHS are not the same as each other; 16 x + 7 = 16 x 7 16x+7 = -16x-7 so zero is the only solution.

@Oofmation Animation Tip: Do not put spaces between lines when you format a paragraph. That is well expected if you do it. You may also use LaTex to format you question like this: 16 x 7 = 16 x 7 -16x-7=-16x-7

Can you explain? I know the question is whether they are equal on both sides or not but how was I lent to write it as an answer
