Question
Solve the equation
Solve for n
n=1
Evaluate
2(3−n)−9=−5n
Move the expression to the left side
2(3−n)−9−(−5n)=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
2(3−n)−9+5n=0
Calculate the sum or difference

Evaluate
−2n+5n
Collect like terms by calculating the sum or difference of their coefficients
(−2+5)n
Add the numbers
3n
−3+3n
−3+3n=0
Move the constant to the right-hand side and change its sign
3n=0+3
Removing 0 doesn't change the value,so remove it from the expression
3n=3
Divide both sides
33n=33
Divide the numbers
n=33
