5a-a-2a=18
5a-a-2a=18
5a - 3a = 18
2a = 18
a = 18/2
a = 9
873 divided by 24
that's 36.375
To solve the equation 5a - a - 2a = 18, we need to simplify the expression on the left side and then isolate the variable "a".
Step 1: Combine like terms on the left side.
5a - a - 2a simplifies to 2a.
Now our equation becomes:
2a = 18
Step 2: Solve for "a" by isolating it.
To isolate "a", divide both sides of the equation by 2:
2a/2 = 18/2
This simplifies to:
a = 9
Therefore, the solution to the equation 5a - a - 2a = 18 is a = 9.
