How do you solve #-32- 4n = 5( n - 1)#?
First, distribute 5 to (n -1), per PEMDAS. You should now have:
We want to negate the lowest variable in order to solve for n. Add 4n to each side to negate -4n. You should now have:
Add 5 to each side to negate -5.
Divide by 9 to isolate for n.
To solve for the variable
Begin by using the distributive property to eliminate the parenthesis.
#-32 -4n =5(n-1)
Now use the additive inverse to place the variable terms on the same side of the equation.
Now use the additive inverse to place the numeric terms on the same side of the equation.
Use the multiplicative inverse to isolate the variable.
