Answer:

Step-by-step explanation:

-4 > x / -7....multiply both sides by -7, and flip the sign

-4 * -7 < = x

28 <  x....or x > 28

yes, they are both the same.

28 < x ....this is saying that 28 is less then x

x > 28....this is saying that x is greater then 28

so there both saying the same thing

25 - 4x = 15 - 3x + 1 - x
kenny6666 [7]

Hello!

To solve algebraic equations, we need to first, simplify the common terms, and secondly use SADMEP. SADMEP is strictly used to solve algebraic equations, and is used like PEMDAS. SADMEP is an acronym for subtract, addition, division, multiplication, exponents, and parentheses.

25 - 4x = 15 - 3x + 1 - x (simplify the common terms)

25 - 4x = 16 - 4x (subtract 16 from both sides)

9 - 4x = -4x (add 4x to both sides)

9 = 0 → This means that there is no solutions.

Therefore, this equation has no solutions, which are contradictions because those are the equations with no solution.
