Question

What is the reason for each step in the solution of the equation?

Answer 1

2x-1=4(x+1) Given. This is the expression you were originally given. 2x-1=4x+4 Distributive Property You distributed the 4 in the subexpression 4(x + 1) to make 4x + 4 2x=4x+5 Addition or Subtraction Property of Equality You added 1 to both sides of the equation. â’2x=5 Addition or Subtraction Property of Equality You subtracted 4x from both sides of the equation. x=-5/2 Multiplication or Division Property of Equality You divided both sides by -2.

Answer 2

Answer:

2x - 1 = 4(x + 1)      Given

2x - 1 = 4x + 4       Distributive Property

2x = 4x + 5           Addition or Subtraction Property of Equality

-2x = 5                  Addition or Subtraction Property of Equality

x = -5/2                Multiplication or Division Property of Equality

- I took the test, these should be right.
