answer:

x = 3

y = 6

step-by-step explanation:

we have two equations —

y = 2x

3x - y = 3

we have to use substitution so we will replace y with 2x since y = 2x

3x - 2x = 3

now that we have like terms, we can solve this to find x

3x - 2x = 3

x = 3

now, we will use this to find y

y = 2x

y = 2(3)

y = 6
