Solve for a. a + (-1.3) = - 4.5 Enter your answer in the box.

We want to solve for the variable a. Which means, we will need to algebraically manipulate the equation where a is on one side and everything else is on the opposite side.

So, we have this equation here: a + (-1.3) = - 4.5

What could we do to get a variable alone? Well, we could add 1.3 to the left-hand side to take out the - 1.3. But, everything thing you do on one side, you do to the opposite side. So, we keep the equation true.

a + (-1.3) + 1.3 = - 4.5 + 1.3

a = - 3.2

So, now we have arrived at our answer. The variable a is - 3.2.

Add 1.3 to each side and get a = - 3.2
