Answer:
(- 8, 8 )
Step-by-step explanation:
Given ( ?, 8 ) is a solution. To find x substitute y = 8 into the equation, then
- 4x - 8 = 24 ( add 8 to both sides )
- 4x = 32 ( divide both sides by - 4 )
x = - 8
Thus solution is (- 8, 8 )
Find b of y = mx + b first using a modified version of the equation.
b = y - mx
b = -1 -(1.2×-3)
b = 13/5 = 2.6
y = 1.2x + 2.6 ← result of substituting values of m and b into y = mx + b
-1.2x + y = 2.6 ← result of subtracting 1.2x from both sides
12x - 10y = -26 ← result of multiplying previous equation by -10
6x - 5y = -13 ← result of dividing previous equation by 2
ANSWER: 6x - 5y = -13

Answer:
Policeman A = 56 tickets
Step-by-step explanation:
Policemen A + B = 70
If Policeman B hands out x no of tickets...
Then Policeman A hands out 4x no of tickets
meaning...
x + 4x = 70
5x = 70
x = 70/5
x = 14
Therefore Policeman A hands out..
4x = 4 × 14 = 56 tickets
