Find the value of x and y <br> x+4y=21, 4x-16=y
Sophie [7]
Answer:

x = 5, y = 4

Step-by-step explanation:

x + 4y = 21

4x - 16 = y

x + 4(4x - 16) = 21

x + (16x - 64) = 21

(17x - 64) = 21

17x = 85

x = 85/17

x = 5
___________________

x + 4y = 21

5 + 4y = 21

4y + 5 = 21

4y = 16

y = 16/4

y = 4
