Answer:

y=0 and x=5

Explanation:

x=4y+5

7(4y=5)-2y=35

28y+35-2y=35

26y=35-35

y=0

for x:

x-4y=5 (substitute)

x-o=5

x=5

(5,0)

Answer:

y=0 and x=5

Explanation:

multiplying equation 2 by 7 and subtracting it from equation 1 we get

7x-2y=35 - 7x-28y=35

26y=0

y= 0/26

y = 0

putting value of y in equation 1

7x -2(0) = 35
