The solution is x = 4 and y = -1

Step-by-step explanation:

The system of equation is:

  • y = [tex]\frac{1}{2}[/tex] x - 3
  • y = x - 5

To solve it using the elimination method do that

y = [tex]\frac{1}{2}[/tex] x - 3 ⇒ (1)

y = x - 5 ⇒ (2)

- Subtract equation (1) from equation (2) to eliminate y

∵ y - y = (x - [tex]\frac{1}{2}[/tex] x) - 5 - (-3)

- Remember (-)(-) = (+)

∴ 0 = [tex]\frac{1}{2}[/tex] x - 5 + 3

∴ 0 = [tex]\frac{1}{2}[/tex] x - 2

- Add 2 to both sides

∴ 2 = [tex]\frac{1}{2}[/tex] x

- Multiply both sides by 2

∴ 4 = x

x = 4

- Substitute the value of x in equation (1) or (2) to find y

∵ y = 4 - 5

y = -1

The solution is x = 4 and y = -1
