Answer:
14.5
Step-by-step explanation:
When solving this we need to use the substitution method. So let's substitute 3 for x and 3 for y.
4x - y / 2y + x
4 ( 3 ) - 3 / 2 (3) + 3
12 - 3 / 6 + 3
Using the method PEMDAS we know to solve the parenthesis first.
12 - 3 / 2(3) + 3
12 - 3 / 6 + 3
Using the method again we know to divide before we add or subtract,
12 - 3 / 6 + 3
12 - 0.5 + 3
Then we subtract
12 - 0.5 = 11.5
Lastly, we add the remaining numbers
11.5 + 3 = 14.5
Hope this helps :)
