V^2 + 3v - 4 = 0 can be factored: (v+4)(v-1) = 0. Then v = -4 and v = 1.
Answer:
Step-by-step explanation:
Initial price is b and discount is 15%.

Answer:
y=9
Step-by-step explanation:
Isolate the variable by dividing each side by factors that dont contain the variables
move variable to left side and change its sign
42-7y+3y=6 collect like terms
-7y +3y=6-42
-4y=6-42
-4y=-36 divide both sides of the equation by -4
y=9
