Solving Equations (Steps)

What is the first step in solving this equation?

d - 10 = 1

• add 10 to BOTH sides

• subtract 1 from BOTH SIDES

• subtract 10 from BOTH sides

• add 1 to BOTH sides

What is the first step in solving this equation?

9 + k = 17

• add 9 to BOTH sides

• subtract 17 from BOTH SIDES

• subtract 9 from BOTH sides

• add 17 to BOTH sides

Answer explanation

The 9 is positive!!! So you must subtract 9 from both sides.

What is the 1st step in solving this equation?

2b + 9 = 3

• add 9 to BOTH sides

• divide BOTH SIDES by 2

• subtract 9 from BOTH sides

• subtract 3 from BOTH sides

2b + 9 = 3

• 1) add 9 to BOTH sides

  2) divide both sides by 2

• 1) divide BOTH SIDES by 2

  2) add 9 to both sides

• 1) subtract 9 from BOTH sides

  2) divide both sides by 2

• 1) subtract 3 from BOTH sides

  2) divide both sides by 2
