Answer:
10
Step-by-step explanation:
Plug in 5 for x, and 10 for y in the expression:
5 + 7(5) - 3(10)
Remember to follow PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponent (& Roots)
Multiplication
Division
Addition
Subtraction
First, Multiply:
7 * 5 = 35
-3 * 10 = -30
5 + 35 - 30
Combine like terms:
(5 + 35) - 30
40 - 30 = 10
10 is your answer.
