Ax^2+bx+c=0
expanded, that is the x term
in
(ax+c)(dx+e), the coefient of the b term is cd+ae
so
(2x-1)(1x+5)
the b term is (-1)(1)+(2)(5)=-1+10=9
b is 9
Answer:
y = 
Step-by-step explanation:
Given
3(y + 2x - 1) = x + 5y ← distribute left side
3y + 6x - 3 = x + 5y ( subtract 5y from both sides )
- 2y + 6x - 3 = x ( subtract 6x - 3 from both sides )
- 2y = - 5x + 3 ( multiply through by - 1 )
2y = 5x - 3 ( divide both sides by 2 )
y =
