Val says that the model below represents the equation Negative 2 x + 7 = 3 x + (negative 4).
Tia says that the model represents the equation 7 minus 2 x = (negative 4) + 3 x.
2 negative x tiles and 7 positive 1 tiles = 3 x tiles and 4 negative 1 tiles
Who is correct, Val or Tia?
Only Val is correct.
Only Tia is Correct.
Both Val and Tia are correct.
Neither Val nor Tia is correct.
Both Val and Tia are correct (the two equations are equivalent).
Which equation is modeled below?
1 negative x tile and 1 positive 1 tile = 2 x tiles and 3 positive 1 tiles
Negative x + 1 = 2 x + 3
x + (negative 1) = 2 x + 3
x + (negative 1) = 3 x + 2
Negative 2 x = 2 x + 3
Negative x + 1 = 2 x + 3
What do the four yellow tiles in the model of the equation below represent?
3 long x tiles and 4 square 1 tiles = 2 negative 2 tiles
–4
4
–4x
4x
4.
What is the solution to the equation represented by the model below?
3 x tiles and 8 positive 1 tiles = 4 x tiles and 6 positive 1 tiles
x = negative 14
x = negative 2
x = 2
x = 14
x = 2
Which could be the first step in solving the equation represented by the model below?
3 x tiles and 4 positive 1 tiles = 2 x tiles and 6 positive 1 tiles
Add 4 negative unit tiles to both sides.
Add 4 negative unit tiles to the left side, and add 6 negative unit tiles to the right side.
Add 4 positive unit tiles to both sides.
Add 6 negative unit tiles to the left side, and add 4 negative unit tiles to the right side.
