A(b-c)=d
We are trying to leave c on one side, so we have to divide by A on both sides first to get
b-c=d/A
now we can subtract by b on both sides to get
-c=d/A-b
now multiply both sides by -1 to get
c=-d/A+b

Answer:
(x = -11 and y = 56) or (x = 1 and y = -4)
Step-by-step explanation:
The equation of the parabola is 10 + y = 5x + x² ........(1)
And 5x + y = 1 ....... (2) is the straight line.
We have to find solutions to equations (1) and (2).
Now, solving equations (1) and (2) we get, 10 + (1 - 5x) = 5x + x²
⇒ 11 - 5x = 5x +x²
⇒x² + 10x - 11 = 0
⇒ (x + 11) (x - 1) = 0
Hence, x = -11 or x = 1
Now, from equation (2),
y = 1 - 5x = 1 - 5(-11) = 56 {When x = -11}
And, y = 1 - 5(1) = -4 (When x = 1}
Therefore, the solution of the system are (x = -11 and y = 56) or (x = 1 and y = -4) (Answer)

Answer:
Step-by-step explanation:
Population(pop) = 800,000 people
Growth rate=7℅
Pop growth in a year= ((100+7)÷100) × 800000 =856000people
Pop in 20 years = 856000×20
=17,120,000 people
