Answer:
2/1 or 2
Step-by-step explanation:
8/4 is 2
9/9 is 1
3x = [(6×6) + 540] ÷ 8
To simplify this, you must first multiply what is in the parenthesis.
3x = [(36) + 540] ÷ 8
Now, you have to add what is in the brackets.
3x = 576 ÷ 8
Divide
3x = 72
Divide both sides by 3 to solve for x
x = 24
In the example I gave (it's an original example, I did not copy from anywhere), the 36 and 540 are added together before being divided by 8. If the brackets were not there, 540 would have been divided by 8 and then added to 36 because of pemdas, which would have given us a completely different answer.

Step-by-step explanation:
Step-by-step explanation:
x²+2x-3=0
(x²+3x)-(x-3)=0
x(x+3)-1(x+3)=0
(x-1)(x+3)=0
x=1 or x=-3
