a=08−3a=0
Solve the equation
More Steps

Evaluate
8−3a=0
Move the constant to the right-hand side and change its sign
−3a=0−8
Removing 0 doesn't change the value,so remove it from the expression
−3a=−8
Change the signs on both sides of the equation
3a=8
Divide both sides
33a=38
Divide the numbers
a=38
a=0a=38
Solution
a1=0,a2=38
Alternative Form
a1=0,a2=2.6˙
