Answer:
0 solution
Step-by-step explanation:
Given

Required
Find number of solutions;
The number of solutions can be determined via the value of determinants, D;
Such that

By comparing the general form of equation;

with 
This gives

So;
becomes



The calculated value of D is less than 0;
This implies that
has no real solution
<span>2x − 3y = 6
3y = 2x - 6
y = 2/3 x - 2
slope = 2/3, y intercept (0, -2)</span>
To represent the length of the string, we can use the variable
y.

Y is four times longer than X.
Hope this helps!
Just factor to find the roots
<span>6x² - 6x - 72 = 0 </span>
<span>6(x² - x - 12) = 0 </span>
<span>6(x - 4)(x + 3) = 0 </span>
<span>B: x - 4</span>
