The answer would be 5/27
(If you want me to explain I can)
Hope this helps
Have a great day/night
To make a square for x²+bx=c, add(

)²on both side
in this case, b is-3/4, half of b is -3/8, and (-3/8)² is 9/64, so you add 9/64 to both side.
-4(3-x)+6=2(x-3)
-12+4x+6=2x-6
-6+4x=2x-6
-6+6=2x-4x
0=-2x
0/x=-2
21 because you just multiply the 2 numbers.
The order of operations is:
Parentheses, Exponent, Division, Multiplication, Addition, Subtraction.
Or PEMDAS.
hope it helps!
