How can you isolate a on one side?
a=26
To solve the equation we have to isolate a on one side. By adding 5 to both sides, we can cancel out the - 5 and isolate a.
LHS+5=RHS+5
Rearrange equation
a+(- b)=a-b
Add terms
Therefore, a=26 is the solution to the equation. To check that we have the correct solution, we can substitute a=26 into the original equation and simplify.
a= 26
Rearrange equation
a+(- b)=a-b
Subtract terms
Since the left-hand side and right-hand side are equal, a=26 is the correct solution.
