Question
Solve the equation
x=−1720
Alternative Form
x≈−1.176471
Evaluate
12−(x−8)=−2×9x
Subtract the terms
More Steps
Evaluate
12−(x−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
12−x+8
Add the numbers
20−x
20−x=−2×9x
Multiply the numbers
20−x=−18x
Move the variable to the left side
20−x+18x=0
Add the terms
More Steps
Evaluate
−x+18x
Collect like terms by calculating the sum or difference of their coefficients
(−1+18)x
Add the numbers
17x
20+17x=0
Move the constant to the right side
17x=0−20
Removing 0 doesn't change the value,so remove it from the expression
17x=−20
Divide both sides
1717x=17−20
Divide the numbers
x=17−20
Solution
x=−1720
Alternative Form
x≈−1.176471
