y=11
Step-by-step explanation:
To find the value of y when X=20, I would substitute “20” for “X” in the original equation (X = 9 + y) and solve for y. So, 20 = 9 + y. then, y = 11.

4x² + 23x = -28
4x² + 23x + 28 = 0 move all terms to one side.
4x² + 16x + 7x + 28 = 0 split the second term into two terms
4x(x + 4) + 7(x + 4) = 0 factor.
(x + 4)(4x + 7) = 0 factor.
x = -4, -7/4
