How is solving a two-step equation similar to solving a one-step equation?

Answers

Answer:

Because it is the same concept, now u have to do more work.

For example

1+1 would be a one step equation

and

1+1(5) would be a two step equation

it's just a bit more.

Each step in solving an equation is like solving a one-step equation so solving a two-step equation is similar to solving a one-step equation

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation

We have,

Two steps equation.

Example:

2 + 3 - (3 x 4)

Step 1:

2 + 3 - 12

Step 2:

5 - 12

-7

One-step equation.

Example:

2 + 4

Step 1:

2 + 4

We see that,

Solving a two-step equation is similar to solving a one-step equation because, in the two-step equation, each of the two steps is like one step individually.

Thus,

Solving a two-step equation is similar to solving a one-step equation.
