Solve the equation and show your work. tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither 4x + 8 = 2x + 7 + 2x - 20

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.

answer. d.289 hope that

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
