Solve the equation
x=5
Evaluate
6x−8=5x−3(x−4)
Move the expression to the left side
6x−8−(5x−3(x−4))=0
Subtract the terms
More Steps
Evaluate
6x−8−(5x−3(x−4))
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
6x−8−5x+3(x−4)
Subtract the terms
More Steps
Evaluate
6x−5x
Collect like terms by calculating the sum or difference of their coefficients
(6−5)x
Subtract the numbers

Evaluate
x+3x
Collect like terms by calculating the sum or difference of their coefficients
(1+3)x
Add the numbers
4x
4x−8−12
Subtract the numbers
4x−20
4x−20=0
Move the constant to the right-hand side and change its sign
4x=0+20
Removing 0 doesn't change the value,so remove it from the expression
4x=20
Divide both sides
44x=420
Divide the numbers
x=420
