Question
Solve the equation
u=1
Evaluate
5(u−3)−8u=−18
Move the expression to the left side
5(u−3)−8u−(−18)=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
5(u−3)−8u+18=0
Calculate the sum or difference

Evaluate
5u−8u
Collect like terms by calculating the sum or difference of their coefficients
(5−8)u
Subtract the numbers
−3u
−3u−15+18
Add the numbers
−3u+3
−3u+3=0
Move the constant to the right-hand side and change its sign
−3u=0−3
Removing 0 doesn't change the value,so remove it from the expression
−3u=−3
Change the signs on both sides of the equation
3u=3
Divide both sides
33u=33
Divide the numbers
u=33
