Question
Solve the equation
x=4
Evaluate
−2(3x−4)=−4x
Expand the expression
More Steps

Evaluate
−2(3x−4)
Apply the distributive property
−2×3x−(−2×4)
Multiply the numbers
−6x−(−2×4)
Multiply the numbers
−6x−(−8)
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
−6x+8=−4x
Move the variable to the left side
−6x+8+4x=0
Add the terms
More Steps

Evaluate
−6x+4x
Collect like terms by calculating the sum or difference of their coefficients
(−6+4)x
Add the numbers
−2x
−2x+8=0
Move the constant to the right side
−2x=0−8
Removing 0 doesn't change the value,so remove it from the expression
−2x=−8
Change the signs on both sides of the equation
2x=8
Divide both sides
22x=28
Divide the numbers
x=28
