MULTIPLE CHOICE QUESTION

Why do we use inverse operations when solving two step equations?

To isolate the variable

To simplify the constants

To make the equation more complex

To add more steps to the solution

Answer explanation

The goal in solving an equation is to get the variable alone on one side of the equation and a number on the other side of the equation. In order to do this we must isolate the variable by reversing the operations acting on the variable. For example if we have 4x the inverse operation of multiplication is division so we would divide 4x by 4

Solve the equation 2x + 8 =18. What is x?

7

6

8

5

Answer explanation

To solve the equation 2x + 8 = 18, first subtract 8 from both sides to get 2x = 10. Then divide by 2 to find x = 5. Therefore, x = 5 is the correct answer.

If you were to create a two step equation where the value of x =4 what would the equation look like?

2x+4=11

2x+3=11

3x+2=11

3x+3=11

Answer explanation

The correct equation for x=4 would be 2x+3=11. Plugging in x=4 gives 2(4)+3=11, which simplifies to 8+3=11.
