Hello!
To solve for x in algebraic equations, we need to use SADMEP. SADMEP is only used to solve these equation, and our goal is to isolate x. SADMEP is known as: subtraction, addition, division, multiplication, exponents and parentheses.
4x + 8 = 2x + 7 + 2x - 20 (simplify alike terms)
4x + 8 = 4x - 13 (subtract 8 from both sides)
4x = 4x - 21 (subtract 4x from both sides)
0 = -21
This equation has no solutions because 0 is not equal to -21, and is identified as neither because it has no real solutions.
