What is the solution to the system of equations 2x + y = 7 and y = 2x + 3?

To solve the system of equations, we have:

  • Equation 1: 2x + y = 7
  • Equation 2: y = 2x + 3

We can start by substituting the value of y from Equation 2 into Equation 1. This gives us:

2x + (2x + 3) = 7

Simplifying this equation:

2x + 2x + 3 = 7
4x + 3 = 7
4x = 7 - 3
4x = 4
x = 1

Now that we have the value of x, we can substitute it back into Equation 2 to find y:

y = 2(1) + 3
y = 2 + 3
y = 5

So, the solution to the system of equations is:

  • x = 1
  • y = 5

In conclusion, the solution to the system of equations is (1, 5).
