hi! i’m going to assume that the 2 next to the x is an exponent, so forgive me if i answer incorrectly. after plugging in x for -6 your equation should be 4(-6^2+3)-2y (the ^ indicates a exponent)

multiply the exponents and get:

4(36+3)-2y

add the parentheses:

4(39)-2y

multiply by 4:

156-2y

and divide by -2 (to isolate the y)

y=-78

this might be wrong, but i hope it helps :)

Answer:

So you kinda forgot to mention the part where y = -1/2 but the answer is 157

Step-by-step explanation:

4(x^2 +3) - 2y

replace the variables

4(-6^2 +3) - 2 (-1/2)

use PEMDAS to solve

so parenthesis first and exponents  

4(6x6 +3) -2 (-1/2)

4(36 +3) -2 (-1/2)     (since you multiply a - by a - you get a +)

4(39) -2 (-1/2)          (again - and a - is a positive)

4(39) + 1

156 + 1

157     there it is i got a 5 of 5 on my test and have a nice day :D
