Question
Solve the equation
x=4
Evaluate
2(x×1)−4(x−2)=0
Remove the parentheses
2x×1−4(x−2)=0
Multiply the terms
2x−4(x−2)=0
Calculate
More Steps
Evaluate
2x−4(x−2)
Expand the expression
More Steps
Calculate
−4(x−2)
Apply the distributive property
−4x−(−4×2)
Multiply the numbers
−4x−(−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
−4x+8
2x−4x+8
Subtract the terms
More Steps
Evaluate
2x−4x
Collect like terms by calculating the sum or difference of their coefficients
(2−4)x
Subtract the numbers
−2x
−2x+8
−2x+8=0
Move the constant to the right-hand side and change its sign
−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
