The solution to the system of equations is (-3, -5) because the point satisfies both equations
<h3>What is a
linear function?</h3>
A linear function is in the form:
y = mx + b
Where m is the slope (rate of change) and b is the y intercept
Line A:
y = x − 2 (1)
Line B:
y = 3x + 4 (2)
Solving both equations simultaneously gives:
x = -3, y = -5
The solution to the system of equations is (-3, -5) because the point satisfies both equations

The question is incomplete. The complete question is :
A man travels by a car from town A to town B, a total distance of 100 km at an average speed of x km/h. he finds that the time for the journey would be shorter by 25 minutes if he increases his average speed by 12km/h. Find x ?
Solution :
It is given the that the distance between town A and B is = 100 km
His initial average speed is = x km/h
His increased average speed is = 12 km/h
Time is shortened by = 25 minutes
So according to the question,
x-12 = 2500
x = 2512
Answer:
Consider
Amount of Rice (cups) : Amount of Water(cups)
1.2/5
2. 3/7.5=2/5
3. 5/12.5=2/5
4. 8/20=2/5
As in all cases Amount of Rice and Amount of water in cups are same.
i.e⇒ Amount of rice × K = Amount of water, where K is constant of proportionality.
So, Among all the statements
⇒ The amount of rice is the dependent value. The amount of water is the dependent value are correct.
Which means if either of them (Amount in cups) is given we can find other.
