0.18 = -0.2 + 1.9a

Question

solve for a

Answer 1

To solve for a in the equation 0.18 = -0.2 + 1.9a, we need to isolate a on one side of the equation.

First, we can isolate the term 1.9a by subtracting -0.2 from both sides of the equation:

0.18 + 0.2 = 1.9a

Next, we simplify the left side of the equation:

0.38 = 1.9a

To isolate a, we need to divide both sides of the equation by 1.9:

0.38 / 1.9 = a

The final solution is:

a = 0.2
