GED 2 - In-Class Two Step Equations Intro

The opposite (or inverse) of addition is ​ ​ (a)   .

The opposite (or inverse) of subtraction is ​ (b)   .

The opposite (or inverse) of multiplication is ​ (c)   .

The opposite (or inverse) of division is ​ (d)   .

Explain how "evaluating an expression" is different from "solving an equation." (How are evaluating and solving related to each other?)

When evaluating $$4\left(5\right)+2$$ , the first step would be to ​ ​ (a)   and the following step would be to ​ (b)   .

When solving $$4x+2=20$$ , the first step would be to ​ (c)   and the following step would be to ​ (d)   .

What is the first step to solving the equation

What is the best first step to solving the following equation?

$$4a-5=16$$

What is the FIRST step in solving this equation?

What is the first step in solving the following equation

$$\frac{x+4}{5}=20$$

$$12g-5=19$$  

$$\ \ \ \ \ \ \ +5\ \ \ \ +5\ \ \ \ \ \ \ \$$  

$$12g\ \ \ \ \ \ \ =\ 24$$   What is the next step?

$$\frac{2}{3}g+7=19$$  

$$\ \ \ \ \ \ \ \ -7\ \ \ \ -7\ \ \ \ \ \$$  

$$\frac{2}{3}g\ \ \ \ \ \ \ =\ 12$$  

What are the next possible steps?
