Someone please answer quick!!

To solve the given set of equations A. we multiply the first equation by -7 and then add the two equations.

Step-by-step explanation:

Step 1:

take this as equation 1,

take this as equation 2.

If we multiply equation 1 with -7 and add the resulting equation with equation 2, we can eliminate the x variable and determine the value of y.

take this as equation 3.

Step 2:

Adding equation 2 and 3 we get

Now, we substitute the value of y in any of the previous equations to determine the value of x.

If we substitute in equation 1, we get

So for the given set of equations, and

So to solve the given set of equations, we multiply the first equation by -7 and then add the two equations.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
