A-53. Simplify each expression below as much as possible. Record your work in the same way you did in problem A‑51. Homework Help ✎
3y − y + 5x + 3 − 7x
−1 − (−5x) − 2x + 2x2 + 7
6x + 2 − 1 − 4x − 3 − 2x + 2
x − 3y + x + 2y
Flip subtraction to addition.
3y + −y + 5x + 3 + −7x
Remove zero pairs.
2y + −2x + 3
Remember to remove unnecessary signs (Example: x + −2 would be x − 2).
2y − 2x + 3
Follow the steps described in part (a).
Remember a negative multiplied by a negative is a positive.
Remember you cannot add variables with different exponent values. (Example: you cannot add x + x²)
2x2 + 3x +6
Follow the steps explained inpart (a) and remember the hints in part (b).
