<span>Multiply equation(2) with 4 so that coefficient of become same in both the equations(You can make coefficient of y same and can follow the following procedure.)
</span><span>* Subtract (3) from (1)
* </span>Divide both sides by -19
*Subtract 21 from both sides.
*Divide both sides by 4
so the solution is x= 3 and y= -7
Hope I helped you :)

Hello!
This question is an example of function composition.
Given, f(x) = 3x - 5, find f(x - 1). For this problem, we substitute x for (x - 1).
f(x - 1) = 3(x - 1) - 5
f(x - 1) = 3x - 3 - 5
f(x - 1) = 3x - 8
Therefore, the answer is choice D, f(x - 1) = 3x - 8.
The answer is B there is a negative correlation in the scatter plot
