Question

Y = -1/2x + 5 y=4x - 4

Answer 1

x = 2

y = 4

Explanation:

y = -1/2x + 5 (1)

y = 4x - 4 (2)

by subtracting equation (1) from equation (2)

y = 4x - 4

y = -1/2x + 5

- + -

___________

4x + 1/2x - 9 = 0

4x + 1/2x = 9

8x + x / 2 = 9

9x = 18

x = 18/9 = 2

by substituting x in equation (1)

y = 4(2) - 4 = 8 - 4 = 4

thus,

x = 2

y = 4
