Answer: (2, 1)

Step-by-step explanation:

The given equations are

y = - 2x + 5,

y = x/2

We would apply the method of substitution, By substituting y = 1/2x into y = - 2x + 5, we have

- 2x + 5 = x/2

By multiplying through by 2, it becomes

2 * - 2x + 2 * 5 = x/2 * 2

- 4x + 10 = x

Adding 4x t both sides, it becomes

- 4x + 4x + 10 = x + 4x

10 = 5x

Dividing both sides by 5, we have

10/5 = 5x/5

2 = x

x = 2

Substituting x = 2 into y = x/2, we have

y = 2/2 = 1

The answer is (2, 1)
