Question

4. 4x - y = 5
8x - 5y = 1​

Answer 1

Answer:

4x - y = 5    slope=4    y=-5

8x - 5y = 1​      slope= 8/5       y=   -  1/5

Step-by-step explanation:

Answer 2

Answer:

(2,3)

Step-by-step explanation:

4x - y = 5

4x - 5 = y

8x - 5y = 1

8x - 5(4x - 5) = 1

8x - 20x + 25 = 1

8x - 20x = 1 - 25

-12x = - 24

x = -24/-12

x = 2

y = 4x - 5

y = 4(2) - 5

y = 8 - 5

y = 3

check...

4x - y = 5

4(2) - 3 = 5

8 - 3 = 5

5 = 5 (correct)...so it checks out

solution is : x = 2 and y = 3...or (2,3)
