Answer 2

x = 7, y = 2

Explanation:

x= 4y -1

since x is by itself 4y-1 will substitute for x in the other equation x+2y=11

it will become 4y-1+2y=11

+1 +1

add one to both sides since is doesn't have a variable.

it will become 4y+2y= 12 now add 4y+2y

becomes 6y=12

6 6

divide by 6 on each side and you get y=2.

now x=4(2)-1 you will substitute y into the first equation.

x=8-1 subtract 8 from 1 to get 7.

x=7

y=2
