You have the following system of equations:
y = -1/2 x + 4 1/2
2 = y - 2x
In order to find the value of x of the previous system, proceed as follow:
- Solve the second equation for y:
y = 2x + 2
- Replace the previous expression for y into the first equation and solve for x:
Hence, the value of x is x = 1
