Question
Solve the equation
Solve for x
Solve for a
x=a−2
Evaluate
x−(a−2)=0
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
x−a+2=0
Move the expression to the right-hand side and change its sign
x=0−(−a+2)
Solution

Evaluate
0−(−a+2)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
0+a−2
Removing 0 doesn't change the value,so remove it from the expression
a−2
x=a−2
