Answer:
For the given linear equation in two variables, the solution to the system of equations is (-2, -6).
Given :
y = x - 4 ---- (1)
y = 4x + 2----- (2)
Linear equations are nothing but yet another subset of "equations". Any linear calculations requiring more than one variable can be done with the help of linear equations.
The standard form of a linear equation in two variables is of the form. Here, x and y are variables, and a, b and c are constants.
From equations (1) and (2) we get,
x-4 = 4x + 2
x = - 2
Now, from equation (1) we get,
y = -2 -4
y = - 6
The solution to the system of equations is (-2, -6).

The probability of pulling a green marble out of a bag of colored marbles is 2:5. If you were to pull colored marbles out of the bag one at a time, and putting the marble back each time for 600 tries, approximately how many time would you select a green marble?? ( explanation too) 7th grade Math
Answer:
We would approximately pick a green marble 240 times
Step-by-step explanation:
Given from the question the probability of pulling a green marble out of a bag of colored marbles is 2:5
Let us denote the number of trials as X
Now the approximately number of times a green marble can be selected would be
=2/5 times
From the question we are given 600 trials
which implies our x=600
Therefore, the number of times we would pick a green marble is:
2/5 × 600 times
≈ 240 times
Therefore, we would approximately pick a green marble 240 times
