Hey there!
7 + 5(3) - ( 6 - 2) ÷ 2
Let's do PEMDAS to solve this equation!
First step:
parentheses → 6 - 2 = 4, right?
Your problem becomes: 7 + 5 (3) - 4
The next step usually would be "e" for the exponents but since we don't have any, we have to move onto
Multiplication 5(3) = 15, right?
We have
division but we can save that for the last ( you don't have to do this method to solve this equation, by the way!)
Problem becomes: 7 + 15 - 4
Next, we do
addition
7 + 15 = 22, right?
Your problem becomes: 22 - 4
Next we do
subtraction
22 - 4 = 18, right?
Now we can do
division
Good luck on your assignment and enjoy your day!

Answer:
64
Step-by-step explanation:

Graphically: graph your equations and look for the intersections (these are your answers).
Algebraically: set your equations into y = format (below) and plug your values into the quadratic formula.
y = ax^2 + bx + c
(example: y = 2x^2 + 5x + 6; a = 2, b = 5, c = 6)
2 divided by 3 is 66.7%. So the fraction would be 2/3
Replace f(x) with f(3)
f(3) = -3x - 2
This means that you replace any x values with 3
f(3) = -3(3) - 2
Now solve. Multiply first then subtract
f(3) = -9 - 2
(f3) = -11
