Question

Solve the following equation
5(x-1)=4 (x-2)

Answer 1

• x = -3

Explanation:

• 5(x-1) = 4 (x-2)
• 5x - 5= 4x - 8
• 5x - 5 +5= 4x -8 +5
• 5x = 4x -3
• 5x -4x = 4x -3 -4x
• x = -3

- - - - - - - - - - - - - - - - - - - - - - - - - - -

Answer 2

x = - 3

Explanation:

given

5(x - 1) = 4(x - 2) ← distribute parenthesis on both sides of the equation

5x - 5 = 4x - 8 ( subtract 4x from both sides )

5x - 4x - 5 = 4x - 4x - 8 ( simplify )

x - 5 = - 8 ( add 5 to both sides )

x - 5 + 5 = - 8 + 5 , that is

x = - 3
