5a - a - 2a = 18
a = ?
Combine terms.
5a - a - 2a = 2a = 18
divide both sides by 2.
Can you help me with my 4th grade
homework I need help with "In how many different ways can you put a
rabbit, ferret, gerbill, and turtle
arrangements to feed his pets?"
To solve the equation 5a - a - 2a = 18 for the value of "a," we can combine the like terms on the left side of the equation.
Let's simplify:
5a - a - 2a = 18
Combining the "a" terms, we have:
5a - 3a = 18
Now, subtract 3a from 5a:
2a = 18
Next, we want to isolate the variable "a" on one side of the equation.
To do this, we need to divide both sides of the equation by 2:
(2a)/2 = 18/2
Simplifying further:
a = 9
Therefore, the value of "a" that satisfies the equation is 9.
