What is the substitution equation for 7x-2y=35 and x-4y=5

y=0 and x=5

Step-by-step 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

7x - 0 = 35

7x = 35

x = 35/7

x = 5
