To solve the equation −3x+8=14, the first step is to ______ 8 from both sides.
What is subtract?
Solve for y: 10y−4−2y=12
What is y=2?
Fill in the blank to make the equation true: y−__=10, if y=3.
What is −7?
Solve for a: −10=5+3a
What is a=−5?
Fill in the blank to apply the distributive property: 4(2x−5)=__−20
What is 8x?
Find the mistake: To solve x−6=10, a student added 6 to the left side and subtracted 6 from the right side.
What is they didn't do the same operation to both sides (subtracted from one and added to the other)? The correct answer is x=16.
Find the mistake: A student solved 4x+8=20 and got x=12. They correctly subtracted 8 to get 4x=12, but then they multiplied by 4 instead of dividing.
What is they multiplied by 4 instead of dividing by 4? The correct answer is x=3
Find the mistake: When solving 5(x−2)=20, a student wrote 5x−2=20 as their first step.
What is they didn't use the distributive property correctly (they didn't multiply the 5 by the -2)? The correct answer is x=6.
