#a=-2.4#

To solve #4.7=a+7.1# first subtract #7.1# from both sides of the equation.

This gives you the answer #a=-2.4#

To check this answer, substitute #a=-2.4# into your original equation to see if it is mathematically correct.

Check: substitute #a=-2.4# into #4.7=a+7.1#, this gives us

#4.7=-2.4+7.1#

and #7.1-2.4=4.7#

#4.7=4.7#

The answer is correct.
