Question 1

What is a Two-Step Equation?

How to solve a Two-Step Equation?

Answer 1

A Two-Step Equation contains two operations in a equation.

Example: 2x+3 = 7

here x is multiple by 2 and then 3 added to.

To solve it by undo each operation in reverse order.

2x+3 -3 = 7 -3 –> 2x = 4

2x/2 = 4/2 –> x=2

Question 2

How to solve:

3x + 2 = 20

Question 3

How to solve:

25 = 1/4x - 3

Question 4

How to solve?

6 - 3x =21

Question 5

How to solve:

2h +9 = 21

Question 6

How to solve:

2x +3 = 7

Question 7

6x+5 =29

3-5y= -37

2/3x - 5 = 7

Question 8

5 = 4a - 7

16=5x-9

3-8c=35

Question 9

2h + 9 = 21

12 - 3/5p = -27

11 = 2b + 17

Question 10

-17 = 6p - 5

2g - 3 = -19

13 - 3d = -8

Question 11

Cassidy went to the movies with some of her friends. The tickets cost $6.5 for each, and they spent $17.50 on snacks. The total amount paid was $63.00. Solve the equation

63 = 6.5p + 17.50 to find out how many people went to the movies.
