Solution

To solve the system of equations, we need to set the two equations equal to each other because they both equal y.

So, we have:

x^2 + 7 = 4x + 3

Rearranging the terms, we get:

x^2 - 4x + 7 - 3 = 0

which simplifies to:

x^2 - 4x + 4 = 0

This is a quadratic equation in the form of ax^2 + bx + c = 0. We can solve it by using the quadratic formula x = [-b ± sqrt(b^2 - 4ac)] / (2a).

In this case, a = 1, b = -4, and c = 4.

Substituting these values into the quadratic formula, we get:

x = [4 ± sqrt((-4)^2 - 414)] / (2*1) x = [4 ± sqrt(16 - 16)] / 2 x = [4 ± sqrt(0)] / 2 x = [4 ± 0] / 2 x = 2

Substituting x = 2 into the first equation y = x^2 + 7, we get:

y = 2^2 + 7 y = 4 + 7 y = 11

So, the solution to the system of equations is (2, 11), which corresponds to option c.
