Algebra EOC Flashcards Set 1

Front

What are the steps in solving
2x + 6 = -12 ?

Back

Subtract 6 to both sides

Divide by 2 on both sides

 

Answer:  x = -9

Front

How do you solve

2x + 5 = 5x – 10?

Back

Subtract 2x from both sides

Add 10 to both sides

Divide by 3 to both sides

 

x = 5

Front

How do you solve

2(x + 5) + 3x = 4x – 10?

Back

Distribute 2 to parenthesis

Combine like terms

Subtract 4x to both sides

Subtract 10 from both sides

 

x = -20
