Answer:
x = 7, y = 2
Step-by-step 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
