Solve for a. -0.01=-0.9 a-1.9 Answer: a=

Isolate a Operation: Which operation should be used to isolate a? In -0.01 = -0.9a - 1.9, we should first add 1.9 to both sides to move the constant term from the right side to the left side. Add 1.9 to both sides: -0.01 + 1.9 = -0.9a - 1.9 + 1.9Add Constant Term: Calculate the sum on the left side and simplify the right side. -0.01 + 1.9 = 1.89 The right side simplifies to -0.9a since -1.9 + 1.9 = 0. So, 1.89 = -0.9aCalculate and Simplify: Which operation should be used to isolate a now? In 1.89 = -0.9a, we should divide both sides by the coefficient of a, which is -0.9. Divide by -0.9: 1.89 / -0.9 = aIsolate a by Division: Find the value of a. 1.89 / -0.9 = -2.1 a = -2.1

a

\newline

-0.01=-0.9 a-1.9

\newline

Answer:

a=

Isolate a Operation: Which operation should be used to isolate $a$ ? $\newline$ In $-0.01 = -0.9a - 1.9$ , we should first add $1.9$ to both sides to move the constant term from the right side to the left side. $\newline$ Add $1.9$ to both sides: $-0.01 + 1.9 = -0.9a - 1.9 + 1.9$
Add Constant Term: Calculate the sum on the left side and simplify the right side. $\newline$ $-0.01 + 1.9 = 1.89$ $\newline$ The right side simplifies to $-0.9a$ since $-1.9 + 1.9 = 0$ . $\newline$ So, $1.89 = -0.9a$
Calculate and Simplify: Which operation should be used to isolate $a$ now? $\newline$ In $1.89 = -0.9a$ , we should divide both sides by the coefficient of $a$ , which is $-0.9$ . $\newline$ Divide by $-0.9$ : $\frac{1.89}{-0.9} = a$
Isolate $a$ by Division: Find the value of $a$ . $\frac{1.89}{-0.9} = -2.1$ $a = -2.1$
