Question
Solve the equation
x=−398
Alternative Form
x=−0.2˙05128˙
Evaluate
−2(x−8)=−8x×10
Multiply the terms
−2(x−8)=−80x
Expand the expression
More Steps

Evaluate
−2(x−8)
Apply the distributive property
−2x−(−2×8)
Multiply the numbers
−2x−(−16)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−2x+16
−2x+16=−80x
Move the variable to the left side
−2x+16+80x=0
Add the terms
More Steps

Evaluate
−2x+80x
Collect like terms by calculating the sum or difference of their coefficients
(−2+80)x
Add the numbers
78x
78x+16=0
Move the constant to the right side
78x=0−16
Removing 0 doesn't change the value,so remove it from the expression
78x=−16
Divide both sides
7878x=78−16
Divide the numbers
x=78−16
