Step-by-step explanation:
2 + 59 -(-9) = 2+ 59 +9 = 59 + 11 = 70
Step 1) Combine like terms/variables.
7y and -2y are similar, combine them.
7+(-2y)=5y
3x has no similar variables, so it stays the same
3 and 6 are similar, without variables, combine them.
3+6=9
The final answer is 5y+3x+9
Answer:
The estimated answer would be 9
Step-by-step explanation:
The answer I received in the calculator was 8.94422. Since the tenths, place value(9) is closer to 9.0 than 8.0, we round up. I hope this helps you.
