What is something you do that can be set up as a two step equation? How would you set that up as an equation to explain to someone else how it can be solved?

As the name implies, a two-step equation is an equation that is solved in just two steps. There are several two-step equations; an example that can be set up as a two-step equation is a target savings with an initial amount and a constant rate of savings.

To set up the target savings equation, we consider the following parameters (I will assume values for the parameters).

Let x be the number of savings.

----- the equation

Mathematically, we have:

The equation is solved as follows:

The first step is to isolate the variable term by subtracting 50 from both sides

So, we have:

The second step is to solve for x by dividing both sides of the equation by 2

This means that you have to save $2 in 475 times to reach the target amount

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
