Answer:

Step-by-step explanation:
Firstly, we know that the solution cannot contain
as when x=3, the equation is undefined. This cuts the options in half
When we plug in a value that is less than 3, we always get a value less than 1. This means that when added to 3, we will always get a value less than 4.
3 times 10 is 30, 7 times 10 is 70. There are 30 girls and 70 boys.
If this is your equation:

Solution:
LCD for 5 and 5x is 5x




←cross product
20x + 30 = 5x² + 25x ←simplify with distributive property
0 = 5x² + 5x - 30 ←use inverse operations to collect all terms on one side
0 = x² + x - 6 ←if possible divide by numerical GCF (This case 5)
0 = (x + 3)(x - 2) ←Factor
x = -3 or x = 2
Please check by substitution in original equation... Both work
I’m pretty sure the answer is 9 to 1
