Math HW - Solve for the Variable

The question:

find the number that each variable respresents

2 5/12= (1 1/12 + a)


The answer:

2 5/12 = (1 1/12 + a)

Remove the parentheses on the right side of the equation – they are not necessary.

2 5/12 = 1 1/12 + a

Subtract 1 1/12 from each side of the equation.

2 5/12 - 1 1/12 = 1 1/12 - 1 1/12 + a

2 5/12 - 1 1/12 = 0 + a

2 5/12 - 1 1/12 = a

1 4/12 = a

1 1/3 = a


The final answer is: a = 1 1/3


As a final step, check the work by substituting 1 1/3 for a in the original equation. The equation will balance (the left side will equal the right side) if the solution a = 1 1/3 is correct.

2 5/12 = 1 1/12 + a

2 5/12 = 1 1/12 + 1 1/3

2 5/12 = 1 1/12 + 1 4/12

2 5/12 = 2 5/12


Since 2 5/12 does = 2 5/12, the solution of a = 1 1/3 is correct.



Thanks for writing.
