What is the value of x in this equation: 4x + 5 = 3x + 4? Solve the equation using the algebra tiles.

Answer 1

Answer:

x = -1

Step-by-step explanation:

4x + 5 = 3x + 4

      -5           -5

4x =    3x -1

-3x =   -3x

1x = -1

x = -1

Answer 2

Answer:

x=-1

Step-by-step explanation:

4x+5=3x+4

subtract 3x from both sides of the equation

4x+5=3x+4

-3x      -3x

x+5=4

subtract 5 from both sides of the equation

x+5=4

 -5    -5

x=-1
