Question
Solve the equation
x=−45
Evaluate
180−(90−2x)=0
Subtract the terms
More Steps
Evaluate
180−(90−2x)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
180−90+2x
Subtract the numbers
90+2x
90+2x=0
Move the constant to the right-hand side and change its sign
2x=0−90
Removing 0 doesn't change the value,so remove it from the expression
2x=−90
Divide both sides
22x=2−90
Divide the numbers
x=2−90
Solution
