Answer:
x = 2
y = 0
Explanation:
2x + y = 4
3x - y = 6
- Add first and second equation up.
- 2x + y + 3x - y = 4 + 6
- 5x = 10
- Notice how +y was eliminated by -y.
Divide both sides of the equation with 5:
x = 2
- To find the value of y, replace x with 2 in the first equation.
2×2 + y = 4
4 + y = 4
- Subtract 4 from both sides.
y = 0
