How do you solve #a+7=16#?

Answer 1

#a = 9#

#a + 7 = 16#

We want to solve for #a#. To do so, we need to make #a# by itself, meaning that we have to subtract #7# from both sides of the equation.

#16-7 = 9#, so: #a = 9#

I hope this is useful.

To solve the equation a + 7 = 16, you need to isolate the variable "a" on one side of the equation. To do this, subtract 7 from both sides of the equation:

a + 7 - 7 = 16 - 7

This simplifies to:

a = 9

Therefore, the solution to the equation is a = 9.
