Answer:
are u useing triangle proportionality?
Step-by-step explanation:
A, the student failed to distribute. In his step one, he got 3x + 2 =y, but it's actually 3x + 6 = y
I got this by distributing 3 to both x and 2, which is 3x and 6.
Your answer:
<span>Equation:
x(x+1) = 2(x+1)+77
-----
x^2+x = 2x+79
x^2-x-79 = 0
------
This quadratic does not have an integer solution.</span>
