3(n-5)+7y has 2 terms.
-2(3x+5)+10(a+b) has also 2 terms. Because they are doing distributive property, they only count as 1 term all together. :)
The order of operation is PEMDAS which means:
P - Parentheses
E - Exponents
MD - Multiply or Divide from the left to the right
AS - Add or Subtract from the left to right
These are the steps of finding the equation you are solving
1) -2x = 34
The inverse of multiplication is division, so divide both sides by -2.
x = -17
2) y - 3.5 = -2.1
The inverse of subtraction is addition, so add 3.5 to both sides.
y = 1.4
3) 2/3z = -6
The inverse of division is multiplication, so multiply both sides by 3z
2 = -18z
z = -1/9
Answer: 63 students
