Question

i want to make sure the following steps for solving linear system
y=3x & x=3y
I think answer is x=9x and y=9y

Answer 1

Answer:

y = x/3

x = 9x

Step-by-step explanation:

y = 3x

And

x = 3y

(1)

3y = x

y = x/3

(2)

y = 3x

x/3 = 3x [by putting value of y from (1)]

x = 3x × 3

x = 9x
