A-53.

**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 ✎

3

*y − y*+ 5*x*+ 3 − 7*x*−1 − (−5

*x*) − 2*x*+ 2*x*^{2}+ 76

*x*+ 2 − 1 − 4*x*− 3 − 2*x*+ 2*x*− 3*y*++ 2x *y*

Flip subtraction to addition.

3*y* + −*y* + 5*x* + 3 + −7*x*

Remove zero pairs.

2*y* + −2*x* + 3

Remember to remove unnecessary signs (Example: *x* + −2 would be *x* − 2).

2*y* − 2*x* + 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* + *x*²)

2*x*^{2} + 3*x* +6

Follow the steps explained inpart (a) and remember the hints in part (b).
