PLZ HELP x-5(x-1) = x- (2x-3)

mezya [45]

Answer:

Step-by-step explanation:

x-5(x-1) = x- (2x-3)

x + x *(-5) + (-1) * (-5) = x + 2x*(-1) + (-3)*(-1) {use distributive property}

x - 5x + 5 = x - 2x +3 {Combine like terms}

-4x + 5 = - x +3 {Add 'x' to both sides}

-4x + 5 + x = -x + x + 3

-3x + 5 = 3 {subtract 5 from both sides}

-3x = 3 - 5

-3x = -2 {Divide both sides by (-3)}

x = -2/-3

x = 2/3
